I don't understand you at 100%...but:
If you want to connect only to specific servers, just give them High-Priority (right-click, priority, high)...
To connect to a server you can also do a double-click on it...
Which servers ? You can connect only to 1 server once...
And you see it when you are connected to, if the server ist bold.. (for CVS/SVN version....for 2.1.3 idk...)
