I like to assign various camo schemes to my units at the start of a battle to help me spot them on the map, but it's a time-consuming process, so is it possible to somehow save our camo preferences and simply load them in each time?

Form my own experience, the camo changes will be kept from battle to battle, and from dlc to dlc. So don't worry.

Yes, camo are saved during a campaign.

Can cams be saved in the random mission generator?

The type of camouflage depends on several parameters: the nation, the type of unit, the season of the year and the year, the theatre of operation.
