I understand what you want.
Thank you for the explanation.

However, I'm sorry, I don't feel like making such a move.
Because moving the opponent beyond the scope of "Sell motion" will take the control of the opponent forcibly.

It's okay if you're playing alone.
But it wouldn't be fun if the opponent made by someone else forcibly took control of own wrestler.

Well rather then the player I am controlling go to the top rope and jump, could you make it so the opponent would instead give the player the body slam and then go to the top rope instead and jump and the player I am controlling gets their knees up?

Right now the move has the player I am controlling go to the top rope and jump and I would rather it be the other way around.

"the attacker is the person who puts their knees up"

I can't imagine this part well, so could you explain it in a little more detail ?
Is it a pin move when the opponent is down?

This is great! But could you make a version where the attacker is the person who puts their knees up? Just makes it look a lot better in game. I would love to put this move on some edits who are bigger and don't jump off the top rope.
