Oh please let this happen.  Kill a giza and send the rest of my squad to orbit real quick!  I get all the cryo!  Muahahahahaha!
In all seriousness,  I don't see how useful this would be.  Why would you want to share cryo with someone who didn't help kill?  If they're afk on the planet and you have to start a mission, you can kick them out. I can imagine a lot of scenarios where people will get angry when the squad leader "Accidentally" clicks someone to orbit.  Good idea, though.
 I think it could be useful for someone who is flying 2 pilots at the same time and doesn't want to be bothered to use the other computer to make them land........  that's a joke but also a reality.
