Expand editing of real and created players

I think it would be a great feature to implement editing of playstyles, potential on real and created players. 

For example if the user thought a players potential was overrated or underrated they could decrease it before starting a career. 

This can add to career challenge as it could be used to increase difficulty of career by "locking" players potential to their rating and allowing dynamic potential to take full control. 

Allowing the user to add playstyles would be great  for "fixing" a user's favourite players not having playstyles.

Bonus feature would be editing generic player faces but I understand this may be more difficult to implement.
