If I want the same variables for 2 full game categories, is there a way to either select it so the variables are applied to 2 or a way to clone/copy the previous one?

Nope. Have to set up two sub-variables, one for the first full-game category, and one for the second. Just have to manually duplicate and assign to specific category. (I assume just assigning the subs to all categories is not an option because there are other full-game categories besides those two that would not be relevant).

Ok, thanks.
