More Audino

I Haven’t finished the game yet, so l apologize if this is already added but unlocked later, but it would be nice if, as you gained badges, you could not only pay the level trainer to get X level, but maybe also pay a little extra for a 4th, 5th and 6th Audino of that level, or just have the number increase every 2 badges (3-2, 4-4,5-6 & 6-8) (- is meant to represent “at”)

Though, I doubt you will, cause i’m guessing there’s some kind of balance thing i’m not able to understand. Figured i’d ask anyway though, just in case.
