Is there any way to change a main category into a subcategory without manually re-inputting every run entry from scratch?

Vid explaining everything you need to know about running ZoE2.

I like giant robuts. I speedrun Zone of the Enders: The 2nd Runner. I hope to speedrun more giant robuts. (I'm not really southern.)

This is my main speedrun. I hope you enjoy and if you have any questions about the run, feel free to ask away.
