Hi everybody,
I have an issue with a specific dataverse architecture:
I have 4 tables:
- Project
- Sub project A (with 9 columns) with a Project loockup field
- Sub project B (with 17 columns) with a Project loockup field
- Sub project C (with 5 columns) with a Project loockup field
- Comments
Each sub project are different an defines sub-projects very differents from sub project A to C. This is why I cannot group sub projects in a single table.
just a little sketch:

Comments can be done on sub project A, B or C and also on projects.
How could I (in an elegant way) link comments to various tables avoiding having 4 loockup fields ?
Thank you for your help
kind regards
Quentin
