Generally game-specific questions should be posted in that game’s forum. However, I can tell you that this isn’t happening. The mods aren’t going to add hundreds of almost-identical categories. If there’s a specific obtain item category you want, and you can explain how it is different enough to be worth running, then that single new category could be possible.
