Option to always directly allow joining in multicrew

Hey,

Now that there are more and more multicrew planes coming to DCS it would be nice option to always allow a set people to join your aircraft without having to go through the trouble of accepting the request.

Usually it isn't an issue but every once in a while someone joins midflight and some of those times don't necessarily make it easy to reach for the mouse especially in VR.

This could be (maybe) done by sorting players by their player id and at the same time we could block the non wanted players from even trying to slot so that the prompt window doesn't even come up.

Can "Accept" or "Decline" be bound to keys or buttons? If not, should they be able to?
