Not accepting rescued pawns from other factions.

[Hilvon1984]

Can we not accept rescued pawns into the colony?
I know this is kind of a rare edge case, but I had a visitor delegation in the colony, then they decided to leave at the same time as raider were begginnig their assault. The delegation got partially killed, partially downed, I got my -15 to relation due to "Chief" being angered. I rescued whom I could, hoping that when I patch them up and they eventually leave this will get me some relations back...
But instead of this all the resqued guests decided to stay with me for good.
And none of them were the people I actually wanted to be around my colony.
I could banish them, but that hurt the mood of my other colonists.

So... Maybe when a rescued pawn can join the colony, it should be not a simple popup that states the result, but a dialog that lets you see the info about potential recruit and either accept or turn them down.
