Build a custom group where members must be a member of two other groups.

We are building a new AC 9.5 installation.  We are integrating with our Windows AD as the directory service and sync'ing users and groups.  We already have AD groups for each department.  We need to create a group for different roles in our organization, like nurses, paraprofessionals, staff.  Is there a way to create a group in AC 9.5 that would have members in it that were part of two groups but only if they were a part of both groups?  So, we could have three groups: All Employees, ICU and Nurses.  Nurse Betty is a member of all three of these groups.  Our education department needs to assign education to all nurses in the ICU but not all nurses or all employees.  So, we would need a group that consisted of the users that were in BOTH ICU and Nurses groups.  Is this possible in AC 9.5?
