collaboration grading does not support Groups feature

Hi,
Just have an unpleasant experience, Scenario details below

Scenario
Doing a long form project and we made Multiple group (on project owner system) of shots to do quicj grades like pre group and Post Group for similar shot.

Issues
1) Assistant colorist (as collaborator), did color graders of a scene, when we tried to publish the group and found out that color grade in post or primary group are not getting updated on main/owner, Only Clips can be updated and worked, Seems like Resolve not supporting the group grades.

Is there anyone faced the same situation, Looking for BMD reply as well.

Thanks for let us know.

I did not try groups in the collaboration mode...

Pls any feedback from BMD on this?
