Feature Request - Decouple Groups from Pages so that Groups can appear on many Pages

### Description

It would be awesome to decouple Groups from Pages so that Groups can appear on many Pages

_OR_

To make groups linkable on other pages. I have some nice tab groups that I would like to appear on multiple pages for different people/users/usertypes without duplication.

Seems like a simple request - but I don't have any idea how destructive to the current architecture it would be... I can't find any duplicate FR.

Many thanks for DB2 - it is becoming quite amazing.
