SetTickGroup in a FTickableGameObject?

I’ll cut to the chase: SetTickGroup is a member of AActor, and FTickableGameObject seems to have no logic for tick groups. I have a object that needs to run some logic at the end of the tick, so I need to set its tick group. Is there some way to do this without doing something “hacky” (like having a dummy AActor with the correct tick group call an event every tick on the object)? Since the object ticks, it has to fall within some tick group I assume, so somewhere in the engine the tick group for FTickableGameObjects has to be defined.
