Converting Training?

I have a quick question.
So I know if you convert a horse's training from, say, dressage to western and such, the stats will be arranged.

I was wondering if you are able to convert training from driving to driving again, and if so does it rearrange the stats?
Thanks, Bandit

You would have to convert from driving to another specialty (10k) then back to driving (2 cr). This can only be done if the horse has never been converted before.  Assuming tge horse is a Foundation, this (expensive!) process would indeed rearrange the stats favorably for driving.
