So, having nothing better to do, I've started working towards all of the "complete all Helmgart campaign maps in this difficulty with that career" challenges, and I thought it'd be a good idea if we had a way to check exactly, for each map, in which difficulty it's been done for each career separately? (instead of the current way, where you only know the highest difficulty you've done that map, but not with who or using which career)

I understand well that it would probably not be retroactive with already completed maps and wouldn't help me with what I'm doing, but I'm sure other people would benefit from it.
