Allow position (number) change after developing player to match new position characteristics

Considering how expensive it can be to buy players at certain positions, it's quite evident that we should be able to act like in the real world and train a promising player from a si liar position to be good at a new position and then reassign the player's number so he can be more easily be be picked up as a substitute in that position or be sold on the market in that position.
You can do that already!

That was my initial reaction but I think he means / suggests that you actually then change the players' designated number as well as the position you play him at.

Exactly. We can train a player for another position and assign any player to any position, but we can't just assign a number to keep track of the fact that the former center is now a fullback.
