So I see there's categories for the individual story types as well as an Any%, is there any specifically for glitchless or is that just part of the general story categories? Been wanting to run All Stories for a good while in the "actually run the levels" style, so I figured it would be good to check where I'd submit that once I start actually doing runs.

look at category extensions, there is a "Restricted" category that might be in line with what you want.
