I don't think there's a way to do this yet, if so disregard. But, I think it'd be nice to have some presets that you can set for each unit group. Like pump out a group of space marines, hit preset 5 and it'll bump the squad up to 6 members and arm half of them w/ missiles.
Hit preset 4 and it'll bump the squad up to 7 members and have 2 w/ a certain weapon and the rest default.
I know I could just click and queue up the upgrades and mods, but this way would be oh so cool?
