I use Livesplit. I know the basics. I can configure my screen, enter in a short list of splits, etc. What I can't -- or at least don't want to -- do is manually enter several hundred splits through the Edit Splits menu. I'm looking to do a 100% run of a very long metroidvania, and the splits are doubling as my notes so I don't forget anything. I've got the route planned out. I'm just really hoping I can type this up in a text file, which would be way easier to do, and just bring it in. Google searches show ways to import from other programs, but not from a basic text file, so I figure I might as well ask here.

So, just a stupid question, but is it possible to do a "No DLC" run on any but the base game maps? Could you just disable every DLC other than the one the map is from?

Only asking because it seems funny there's all those options on the leaderboard, but they seem like they're effectively impossible.
