...as far I can see it's impossible? Would it be too much to ask to make it possible?
The reason is after the previous battle I tend to have messy situation with my equipment. I need to patiently move all the loot to the correct unit and check all my weapons and other supplies status etc and move them accordingly if only needed. After this I have to select the correct units and place them in correct starting positions... and all of this at once. And if I do some kind of mistake here - boom, I have to restart with all of this from the begining. Not especially rewarding experience... if I could somehow save at least after I do all the equipment stuff it would be much apprieciated.
