How to force wrecking ball into his ball and another Q

I have two simple questions for the workshop.

1. How do you force wreckingball into a ball, which he can never leave.
Note that I want to use code. I do not want to touch the “always in role” to true in settings. This is because I want the players to leave ball form later in a game.

2. Can you force something to become potg
I tried with code killing all players which were “done” by the host. So in the kill feed it says the host killed all. Somehow this doesnt become the POTG (Play of the Game).
