Collaborative Culling (Setting Flags, Stars, Color Categories, and Deleting)

I would like to be able to do the culling process across multiple users. A couple of things would solve this. Having Adobe Cloud Folders with Owner permissions viewable from Lightroom CC via the local folder, or having shared folders retain the metadata shared between Lightroom with a (multiple owner) permission would be great.

The goal is to have someone be able to help in the culling process. Lightroom CC is quite nice since the interface is much better than Lightroom Classic, but it’s being hampered by not being able to cull collaboratively. Which is sometimes the hardest work in the process. The AI tools do not work for the workflow we have.

In either case having someone be able to Pick Flags, Set Ratings, Set Color Categories, or choose files to delete would be more than nice.

For the alternatives, they just don’t work. We have tried likes and the new collaborative proofing tools or liking and commenting, but neither options works particularly well than having native Lightroom CC options especially flags.
 

Any way to do this would be great.
