Remove levels from spirits of rage

[Valerio80]

I just realized i made some mistakes in choosing spirits' upgrades on their levelup, and now i'm wondering if there is a way to clear them back to level 1 (and then level them back by cheat rearranging upgrades). Anyone?

I think it would be nice to have this possibility with the hero too... a sort of "respec" option... the randomness of the upgrades on levelup is a bit confusing, so it would be nice having at least the chance to respec.
