Is your feature request related to a problem? Please describe.
I'm making an analysis of an algorithm using a mixture of UML & Flowchart.
On the pages that contain flowcharts, I want to see my UML entities (e.g. class definitions / data structures)
Right now, I simply copy / paste these onto each sheet where I want to "see" them because in my flowcharts, I'm referring to properties etc

This of course brings along the hassle that if I want to make changes to these UML entities, I need to replace them everywhere I copied them.

Describe the solution you'd like
Ideally, I want to place my UML entities on a separate "data" page and on other pages where I'm interested in showing these, "refer" to those entities located on my "data" page.
If i then modify these UML entities on the "data" page, the changes are automatically persisted on the other sheets

Describe alternatives you've considered
I've tried putting the same ID on all the copies as the original, but that didn't work as the IDs seem to change quite often 😅

Additional context
Being able to make modifications on the copies and have those changes persist through to the original entity is a bonus, but absolutely not a requirement
