Cheating casual (question)

Hello there.
Keep in mind, I'm casual player who doesn't like fair challenge, WBC3 was fun for spamming hordes of zombies to swarm mighty enemy heroes (AI) with disposable meatblob any casual at heart will find hillarious.

So I decided to try this fancy newly released mod, fairly balanced tbh (booooring making 16 reces same with sprite difference).
Its not that I (cheating casual gamer) care about balance in singleplayer game I play for fun. Cheers to competetive multiplayer WBC3 mod.

The problem is, "Your hero was fixed" when I tried my trusty ArtMoney to add some hundreds of skillpoints. Oh, and on a good side I found a way to freely respec a hero.

So is there some little checkbox to separate fair multiplayers from fun seeking casuals?
If not, consider it a free idea for the upcoming patch. Its first time I've seen singleplayer do this, quite low blow.
