So my vault has 200 dwellers, and I recently got 2 more out of lunch boxes that I opened (neither were legendary). However as I have been working on training my dwellers that I already had the new dwellers have worse stats than those in my vault so it would be a waste to kill off anyone in my vault to let these two in. Is there any way to get rid of these guys standing outside my vault? I don't particularly like having them there and it is a bit annoying that they show up in my dwellers list by I cant let them in or tell them to go away.

Thanks.
