Role based session group filter

I asked for this once before in the forums. Basically I want sessions for specific departments to filter into specific session groups. IE the sale department sessions filter into the sales group. It would seem simple if a user was assigned to the Sales Department role that I could filter by all users in the sales department role. When I asked before the only solution was to add a filter for each individual users (kinda a pain in the butt!).

Here is a link to the original forum post. http://forum.screenconnect.com/yaf_postst4791_Role-based-session-group-filter.aspx#post19061
