For first part of the thread: No. It doesn't exist. OP that mentioned that idea wasn't telling the truth. There is a way, but it's totally not what he was referring to. There is only 1 step, and because it's also game-breaking, cannot talk about it.
As for second part, refer to: https://www.mpgh.net/forum/267-vindic...-commands.html
