Is there any chance for extra categories to be added?

For golden arena, there's no category for difficulty, but the rules are to just clear the mode. This leads to some open ended rules, such as whether or not someone can use a max level character/max social link navigator.

There are harder difficulties that are longer, which would be nice to run. With the current rules, there's no point in running the harder difficulties.

Also, I was surprised to see that there aren't any categories for Score Attack mode, considering there is an in-game timer for that mode. Is there a possibility for categories based on difficulty/Score attack course to be added?

I'm looking to do more runs of this game, and would just like this cleared up.
