At the moment there is a limitation that locks the performance reports view of a member to only see the call queue they are the manager of and will not allow them to see other call queues or users. You can only see them all if the user was removed as a manager of the call queue. It would be best to have a switch that allows them to have the capabilities to switch between the 2 or atleast the super admin would have the option to allow them to see either one through the portal roles and permissions.
