Can we add categories to the leaderboards that allows the 4 (Error Rockets) and 5 (Door Unlocker) key binds that need to be cheated using the console?

no

Why not? I like the idea.

There, I've added a Cheat% category. Hope you like it.

because cheating in speedruns is an illegal thing (for speedrunning). I am removing it, stop adding new things.
