Hi Melissa,
I can confirm BUs and MUs do not affect the Performance Views/Exports and are used for the specific configurations with WEM for Adherence, planning, scheduling, time-off rules etc.
If you only want the Senior Supervisors to access certain queues and the agents on those queues, then I would recommend reading up on Access control overview, but I would be interested in seeing how others have managed this scenario.
