Just for anyone that was interested in this feature, I was trying to do this myself and figured I would use labels in a roundabout way to achieve this. I was hoping to exclude users from seeing a collection that had a label of the other users, but there is a bug that does not apply excludes to pinned items.
If you’re interested in watching the topic it is here: Excluded Collections Should NOT Stay Pinned to Homescreen/Library Recommend - Plex Media Server - Plex Forum
To be clear, if this gets fixed, it can make this feature moot.
