Is it possible to have an IL that has separate categories from other ILs? I'm trying to improve the Lego Star Wars Complete Saga Boards and some levels just play differently and wouldn't be divided into the categories that the other levels are.

IL's within IL's has not yet been implemented, and I don't think there are current plans for it. Be nice if it was available, because it would make sorting the IL's within their own categories nice and easier to set up. Tho I'm not sure how hard it would be for them to add that feature....?

Aight, thanks guys

There has been a good amount of thought to this, but it's a very complex update (not in the near future) involving many modularity changes.
