I think there should be level runs

Personally I don't think that would be a good idea as the game's speedruns aren't that long if you practice them and the main thing going for individual or section runs is lower time and Run (series as a whole.) doesn't have a clear thing separating levels the reason Goldeneye 64 main speedrun category is level runs is because you have to go back to the level selection menu and select another level Run doesn't have that it immediately goes to the next level for those reason I don't think having a individual level or even a section of levels (Example level 1 - 10.) run is a good idea.

I think sections would work too!
