Manage Areas of responsibility - Restrict by Business Units

Content

Hi 

We have an called AoR Benefits Reprensentative.  This AoR has been assigned to an employee who is the Benefits Admin. 

Now we have a Business Unit for whom this Benefits Admin shoud not be showing up as the Benefits Representative.

I tried to do this from the Scope of the Manage Areas of responsibility but could not do since from there we can select a BU not filter.

Did anyone has a similar issue? If yes could you please help me how you handled it?

Thanks
