Show which iModels each role is assigned to

I'm going through our iModels to understand which permissions/roles can be taken off the programme. At the moment, I need to select each iModel individually, check the permissions then make note.

What would be much better, is if on the "Roles" page, there's a column which tells you how many iModels use that role. In the exact same way you can see which users are assigned that role.
