When searching and adding a user group, for Crowd with multiple Applications and Multiple Connectors(though same) it's difficult to spot the correct user

• In customer words-
  With our configuration we have an separated connector for each Atlassian application. But when I want to give a user administration to a local group, the user is shown multiple times, but it's not clear which one I should select. See attachment video

I've got the directory Bitbucket with a connector to the Active Directory and I create a local group with this directory. I want to add a user to that group to administrate the group. But that user must be from the same directory and not another one, for example directory Jira. If the users get's removed from the directory Jira, it also can't administrate the local group anymore.

Adding the Directory Name of the user origin would be great, something like below
_Firstname, Lastname (UserPrincipalName) (Directory 1)
Firstname, Lastname (UserPrincipalName) (Directory 2)
Firstname, Lastname (UserPrincipalName) (Directory 3)_

Currently it shows on below:
_Firstname, Lastname (UserPrincipalName)
Firstname, Lastname (UserPrincipalName)
Firstname, Lastname (UserPrincipalName)_

Hope this should be fairly simple
