Ops-Center - Restrict client access based on User / Group

Using Ops-Center 7.6.1.  Is it possible to configure user access so that a particular user or group of users only have access to certain servers / client?  I guesss it relies on being able to group the clients but I can't see how to do this.  Ideally we want only Team A to be able to execute Restores on Team A's servers and the same with Team B, etc.  We have already added a few Active Directory user accounts.
