There is, it isn't really a secret as that would be all but impossible and, whilst useful to help reconnect with non-kin friends, I'm not really sure it has much long-term utility. We should really try to integrate with our new server population in as mature a fashion as possible and acting like a server-within-a-server ultimately will not be helpful toward that end. That's purely my personal perspective of course, but it makes the most sense to me.
