Separate sections for boundary group preferred site systems or select the role the site system will provide for group
We can assign MP, DP, and SUP to a boundary group as a client preference, but this is all within one section. It would be nice to have this broken up into the roles so we can assign accordingly. If you have servers with multiple roles you may not want clients using every role. If I have Server1 with the MP and DP role in one region and Server2 in another region with just MP. I have a boundary group set to use Server2 for MP and another server for a DP. Server2 goes down and I need to set the boundary group to use Server1 for MP and don't want the clients to use it for a DP, I don't have a real way to do that as preferred site systems are all one section.
