I'm guessing this is not currently possible, but figured I'd ask. I would like to combine AAA server load balancing within a group with an ordered list of address my globally regionalized environment and maintain high availability. For example, i want a user in the US to first auth to the US, then EMEA, then APAC. But I also want to load balance among the servers in each region (e.g. three servers in US). Is this currently possible or do I need to submit a feature request?
