Dear Community,
we are using Confluence 7.19.17 and are currently setting up a knowledge base.
A desired feature would be to track who is responsible for what page (which is fairly easy to manage, by just using the function to @ mention) but in return we would also want a feature that allows to display which pages are under a persons responsibility.
Ideally on the startup page, we would have a dropdown of everyone in the team and pick a person and then see a list of pages in which they they are listed as the responsible person. Thats just a suggestion though, just picking or sorting for a person and then seeing all the pages under this persons responsibility is fine.
So far we have tried to use the page properties macro and then generating a page property report. This way technically works, the necessity to tag pages with a certain word and apply that tag whenever you create a new page is very cumbersome and therefore not practical for everyday use with 100+ people.
Would anyone have suggestions on how to implement this?
I have tried this: Transfer ownership of your page to another person | Confluence Cloud | Atlassian Support
Unfortunately this does not work, as we don't use this version of confluence.
Thank you for any recommendations on how to approach this.
