User management - admin console

I currently have 130 users in Adobe DMS. I would love to be able to group them under the area of the business they work in, so I can easily clean up or get the main contact for each business unit to be able to just manage it.

Is that a possibility? At the moment it says Title - but it would be great to create Department or Business area etc.

Also is it possible to give admin for a user to only be admin for their department / business unit and be able to only admin their report suite instead of all report suites?
