Permissions per Collection

Feature name

Permissions per Collection.

Feature function

Currently Permissions like Manager are for all or for all assigned Collections.
I propose, that these Permissions can be set for each Collection independently.

My use case are different departments which have different Managers, but if Manager1 from department1 is added to a Collection of department2 (from Manager2) he is a Manager there as well. But Manager1 should not be Manager of this Collection.
With this Feature a Escalation of Privileges can be avoided, because if Manager2 adds Manager1 to his Collection as Read-Only User, that Manager1 can change his own access rights to this Collection!

It would be a huge benefit for all larger Companies!
