The Mod has a function where you can choose to store the vehicles that you have when you finish a mission, and then carry them over into your next mission. Is there a way that I can choose the next mission that I play for carrying my stored vehicles onto them.

So for example, the campaign menu for the Mod has a number of Germany, Japan, France, Russia missions, all mixed together. Is there a way that you can win a Germany mission, then store your vehicles, and then choose another Germany mission to play next, and move your vehicles onto it?

I won a Russian mission (Hutor) and then clicked next, and it loaded my vehicles onto the next mission in the campaign list, which was a Germany mission. So I reloaded my Hutor mission savegame, beat it again, saved my vehicles, and then went to the campaign mission and chose a new mission (Glubinka). But unfortunately my vehicles didn't load into that new mission, Glubinka.
