How to link other confluence site sections

[Ignazio]

Hi, 
I would like to link reference to other (company division) confluence site sections where content is sadly not well (or otherwise) struktured. Until now I used 2 methods:

1) copy absolute site links and verbally refer to a section title (very laborious);

2) insert a content directory at page top, open (sub)chapter section in a tab beside and copy link (if page is moved, I loose the link)

Unfortunately I cannot insert a content directory and use method 2); technically ok, other party doesn't want.

Is there a cunning way to solve that? e.g.
A) implementing a shadow content directory and use method 2). How?
B) other ways?
C) is there also a way to address absolutely those sections rsp. be advised sections are moved/deleted or advise party I am using that section, in order to copy that section before deletion? (Link is a better way because information there are usually maintained..)

I thank in advance for any hint.
Regards, Ignazio
