Hello is there a way how to get a new category i have this category in mind for long time even attempted it myself

Its for the game heartstone

Kobolts and Katacombs dungeon

Called K&K Hardcore run

With All 9 characters

Rules should be simple

You die you restart

All 9 classes

Run start when your click play on the first character play button

You should post this in the forum for that game, since ultimately the moderators for that game will decide if it gets added or not. Expect the answer to be "no" though, most games are generally not looking to add new categories.
