(MR/VR) Allow for grabbing like in other VR games.

Currently the grabbing is only on one contoller and tether based.
It would be nice if the game used more standard grabbing mechanic similar to other VR games.
This would allow the player to easily grab things and interact with them.
It would also be helpful for if you want to make games that rely on grabbing objects.
For example when i was testing MRVR version of the game, i made a basketball basket and a soccerball and i wished that i could pick up the soccerball like in the other VR games by just reaching up to it and grabbing it.
