This question is in reference to Atlassian Documentation: Page Properties Macro
I would like to add page properties to an existing page which wasn't created with them in the first place.
For example, adding the page properties from a particular product requirements or retrospectives page to an existing page, and later manually updating some of the copied property fields.
Just copy the page property macro with content from you source page to your target page.
After that, fix the values you need to.
Might be a bit hacky but maybe try the following:
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
