CDK allowed vehicle list?

For missions made in the CDK, how do you create custom allowed vehicle list? I was told that you can use Notepad, but that’s as far as the person told me (big help, right?). I’m still in the process of making an enduring confrontation game mode, on the large ARB berlin map. Its 1960-1991 and I need to be able to select what vehicles are on what team and what wont be allowed.

Thanks so much!
