2 Join group questions

[victim913 10]

Is it possible to make some kind of trigger that any unit that crews a vehicle like a tank, so that if they leave the vehicle they join a different group?

-Say a tank crew loses their tank, they can leave their group and join a group that moves to a rear location. Or boats.

-Anyone abandons ship, they can join a group that is designed specifically for picking up floaters.

Second question is there a way I can use a trigger like radio alpha to have all units of a side join together into one group. That way at the ending of a battle when units are scattered over the battlefield with one or two units left in each group they can band together to be easy to manage.

Thanks
