Following up on my post, I think I see a way to make /server work better in this context. Currently, /server with no parameters tries to find the server in your servers list based solely on the server address. I will extend it so that it tries to find a match based on address, group, and description, in that order of priority. The best matching item in the servers list will be assumed to be the target server. That should resolve the /server issue for identical addresses in different groups that you described.
