How to find anims within nba_animations.iff and siganims_generic.iff files

This is a tutorial, there's no mod being released here.

Oh okay, I finally found the subject and the file I wanted

Probably a bit offtopic, but does anyone know how the signatures even work? Like, is there a way to copy Durant or Curry's pointing to another player? I know you can replace animations with others as in you could replace the generic 3 get back with Durant's point, but is there a way to just copy a player's signatures over to another?
