With the heavy limits on territory these days it is really annoying to give a new allied town territory that you already own. Currently you have to release it and wait 6 hours and take it back, just proposing a way for this process that is less annoying. I've tried to think about how this suggestion could be a negative thing, only thing I can come up with is that I guess a new town could be made in this transfer but the alliance would prevent that from happening anyways. I think this is just a good QoL change.
