Call Recording

I am trying to set up call recording for a particular group in a TB pro setup. I have tried every possible variation of the available permissions with no luck. Here is what I am tryng to accomplish:
I need to give the "support managers" group permission to record, the "support agents" group in the HUD as well as the ACD.
The problem is that, giving the "support managers" group permissions in the ACD, allows them to record calls for every group in the company (not just the "support agents). Even though I have ONLY given them permissions over the "support agents" in the "Group permissions" area.
Is there a way to schedule call recording in the ACD & HUD for just one group, not everyone?
