To be honest, it all started with a lapse of attention. I had done a run of "All act 2" without checking if this category existed, and when I wanted to propose this run, I noticed that this category did not exist. Therefore, I suggest creating the categories "All act 2" and "All act 3."

it certainly does sound like a not so bad idea to have a second and third act% if that's what you are referring to

I was actually talking about that.

Second Act% and Third Act% have now been added as misc. categories.
