Modify dunk and layup packages

Does anyone know how to modify a dunk package? Like, take a dunk animation that belongs e.g. to side arm tomahawks package and move it to straight arm tomahawks package. Also if you can create custom packages etc.

I’ve tinkered with modifying dunk packages before, and it’s totally doable! You can swap animations between packages by editing the animation files in the game's modding tools, but it does require some patience to get the transitions and movements smooth.
