add it as either different category or sub category to LowGravity%
same rules as NoSLA except oob is allowed.
You need to type sv_cheats 1 and sv_gravity 0 before loading container ride save, or just reload it

Is it even possible though?

yes, its another one if those stupidly hard challenges like 100 portals but its possible. You need to go oob though, thats why i want it to be allowed

its a very cool category yes
