Shouldn't this be moved to the main board since APC was moved from the CE board

When I was moving it the only problem with it is that I cannot make a straightfoward ruleset specifically towards APC ILs, it would have to be towards all ILs meaning it would penetrate the other subcategories, it just won't work properly with ILs.

It is possible to:

Enter rules for one category and all levels Enter rules for one level and all categories.

The sum of those 2 features will appear in the ruleset box.
