training players in new positions

ok, so i've just had a thought about training players in new positions.

so say you've got a cm and you want to train him in the left wingback position and he has never played there before, so you choose this position on the training screen and start playing him there week in week out!!

do you think it would make sense if the surrounding areas slightly improved aswell, for example, left fullback would improve slightly and left midfield would improve slightly also.

do you think that would make sense? or do you think it would be too complicated/confusing?

There is attribute Versatility. Determines how well player can learn new positions and play out of his favourite positions. I think that is enough.
