The only thing to do is write down under every turn column the amount of reinforcement/loss the unit takes. Everything is automated with formulas and formattations, nothing is blocked/protected so if something doesn't function it's your fault not mine!
It's adapted for the first scenario of '39 campaign "FallWeiss", I've tried it and it worked well, hope it could be usefull for every other maniac here!
