It would be nice to have an any% for every episode

They're all self-contained in an any% speedrun so there doesn't seem to be a point

I agree, there could be something for tracking it such as a different website, or amongst speedrunners in the CT: TT Discord Server, but I don't think an official category on SRC is necessary. People might compete for nice times and compare them but I personally think that should be kept off of SRC because of the reason above ^^^, and for the fact that they seem like minor categories that not many people would be interested in; it seems like just a part of Any% for me and doesn't seem like anything special.
