sizeup moves

there's special sizeup moves for superstars like LeBron James, Dwyane Wade and Kobe Bryant. how can i edit sizeup moves for Gilbert Arenas? is there some kind of editor for player moves? i'm not referring to the edit player dribble moves in game 'cause it can only change crossovers etc. i want to change the sizeup move.

It might be posible for PC but I have console and it isnt possible. Maybe the handling rating?
