Stances/ Signature styles for other positions.

Why can’t we edit stances & signature styles for other skill positions. It’s available in superstar mode & dynasty for college football for all recruits. Is it really that hard EA to translate that into franchise? It kills the immersion seeing every generated player from the draft have the same exact stance. Please FIX THIS!!! What if I want to draft a running back and have the option to stand like Ashton Jeanty. Nope can’t do that. Or draft a receiver and be able to choose a different stance than just him with hands on his knees. Jesus Christ.
