We need to be able to individually select what categories a variable applies to. Currently you can only select that a variable be applied to 1 category or all categories; If you need a variable to apply to all but one category, there is no great solution. You can either

1. make multiple identical variables that apply to every other category individually. This involves manually updating every run to have the new variables (for the game I moderate this is about 2000 runs, and the api doesn't let you update fields) or,

2. have the variable be optional and tell everyone to leave it blank for the exception category, but to make sure it's filled in for the others (this is confusing for people submitting runs and extra work for moderators)
