Menu to disable quest-acquired resistances

This seems like an odd request, but I started making a witch hunter, and along the way I decided to focus on lightning skills using Doryani's Protoype. However, I now have +20% lightning resistance more than I ideally would want, since the item wants me to have as negative lightning resistance as possible.

While this is a rare case, it is impossible for someone to foresee this need unless you have knowledge in advance. Perhaps you can implement some menu or NPC where you can disable these bonuses? Maybe as part of your respec menu with The Hooded One.
