Move_Route

I was wondering if there was a way of changing the Atoa Overdrive script to reduce the Overdrive bar back to zero after a character uses their move. I would need it to function with Enu's Sideview Battle System using Atoa's ATB. At the current moment it just remains filled until the character faints. My other query was whether it is possible to link QTE's with overdrive skills. I would like the player to be required to complete the QTE sequence correctly to get the full power of the move.
