Units for Multiple Countries at once

I don't know if this has been said before but I just thought of it. What if AtWar added a feature that we could make X,Y,Z units available in A,B,C countries instead of adding a unit to 22 countries then doing it the same with every unit that goes with it. I find it time consuming and boring when im trying to add German units to all the German lands during WW2. Perhaps a copy+paste feature idk something to make it easier.

I'm not active in-game but I support this. Would be cool if this can be added in the game, it would make scenario and map making so much easier.

I am not a premium, but the idea is so brilliant. It would consume lesser time to build a map if this gets implemented.

Support. I think map-makers should get all the motivation they can since they're contributing to the game.

Very important. Full support.
