[REQUEST] Add collisiongroup like old csgo AddOutput>collisiongoup 2 to KeyValue

[ronglucky]

I need collisiongroup 2 for players touching trigger to be able to walk through prop_physics with Debris spawnflags unchecked.
If I teleport player inside a physic prop it will force the prop to fly and stuck.
In csgo there's AddOutput>collisiongroup <number> but I checked cs2fixes doesn't have this KeyValue.
