User-defined Connection Pools

[Permanently]

One more suggestion from me, I promise.

There should be a feature where users can define 'pools' of configurations, so that when you connect to said pool, it'll connect to one of those randomly listed.

E.g., I could have us-1, 2 and 3, and ru-1, 2 and 3. If I create a 'pool' called "Random US server", and added us-1, us-2 and us-3 to it, when connecting to "Random US server" it'll randomize each time between us-1, 2 and 3. But, not ru-1, 2 and 3, as they are not in the list.
