Limit People column to a subset of users

I’d like to be able to select which users are available in a specific people column, either by selecting individually or by selecting a user group.

Great thinking, I also would like this function.

I think this is a very handy quality of life impovement if your team is bigger than 5 people.

Would really like this. We have 60 users, but only a small group might be able to approve things in an approver column.
