Show call groups user is assigned to and add/remove call groups from the user account page

In general, I really wish the user's account page resembled AD a bit more in terms of the information present in one singular location.

Id like to be able to open a user's account and see all the call groups that that user is in. While we are at it, if you could add/remove the call groups from the user's account as well as the call groups page, that would be fantastic. Think "Member of" for users and "Members" tab for groups in AD.
