Adding an article to hierarchy but need the same article to be available in other parent category

[Henry Steinberg]

So I've been looking for a way to organize my space, there are two parent categories and I have one child article under one parent, but is it possible to add the same mentioned child article under the other parent category without making a copy of the child and place it under the other parent but have a link of a child under one parent and then the same link under the other parent that leads to the same article.

so i can access the same article from two parent categories and when I change the article, then both links lead to the same article that was changed.

if I make a copy of a child then if I place the same copy to the other parent and need to have changes in one child, then I have to change the copied one also. I want to avoid doing the same thing twice but do it with one go.

is this solution possible?

IE.
Space observation (parent)

             How to set up the telescope(child) (have to edit this manually)

             Coordinates of the stars(child)

Telescope management (Parent)

             How to set up the telescope(child) (this is linked and no need to change the same one twice)

             How to clean lenses(child)

right now the only solution i can find right now is:

Space observation (parent)

             How to set up the telescope(child)(have to edit this manually)

             Coordinates of the stars(child)

Telescope management (Parent)

             Copy-how to set up the telescope(child-copy)(have to edit this manually)

             How to clean lenses(child)

Pages under overview(asked question):

Space observation

Coordinates of the stars

Telescope management

How to set up the telescope (only one article)

How to clean lenses

Pages  under overview(copy solution):

Space observation

Coordinates of the stars

Telescope management

How to set up the telescope

Copy-How to set up the telescope

How to clean lenses

There's a lot of complexity in your example that I am not sure is actually a problem or relevant, and it's not written in Confluence-speak, which is confusing to me (Confluence doesn't have "category" as you have used it in the question so I'm not even sure what you mean).

So I'm going to take one bit of your example page hierarchy as an example, and paraphrase it back to you to check my understanding.  And hopefully give you a useful answer too.

You have:

Space observation (parent)

             How to set up the telescope(child)(have to edit this manually)

             Coordinates of the stars(child)

Telescope management (Parent)

             Copy-how to set up the telescope(child-copy)(have to edit this manually)

             How to clean lenses(child)

This page hierarchy to my mind, is done in Confluence as 

• Space observation 
  • How to set up the telescope
    • Content: Some text about setting up a telescope
  • Coordinates of the stars
    • Content: a list of stars
• Telescope management 
  • Copy-how to set up the telescope
    • Content: a copy of the page "How to set up the telescope"
  • How to clean lenses
    • Content: some text about lens cleaning

I would change this to:

• Space observation 
  • How to set up the telescope
    • Content: Some text about setting up a telescope
  • Coordinates of the stars
    • Content: a list of stars
• Telescope management 
  • Copy-how to set up the telescope
    • Content: {include page macro: "How to set up the telescope"}
  • How to clean lenses
    • Content: some text about lens cleaning

The line in bold is the one thing I'd change.  I would still create the Copy-how page, but I would use the "include" macro to include the entire content of the original page. 

Any edits/updates to the source page would then be seen automatically in the copy!
