Is there a way to keep the loadout presets between missions?

I like the scenario battles in the new version, but for example in the one where you defend against a horde of dummies, I think it's crucial to get some people in place fast. But each time I have to select the dropships loadouts again and again. Then when I want to give the next guy a sniper rifle instead of an assault rifle, I have to erase the assault rifle, go to weapons, look for the sniper rifle, put that in, perhaps do the same for the body.
How come the presets are erased at the end of the mission? Is there a way to define some default presets that will be available on every mission?

Yeah, Presets could really use some work. Even having some default ones would be great.
