[RMVX ACE] MAKE AN ENEMY USE A SKILL AS SOON AS IT QUALIFIES

I'm playing around in VX Ace at the moment - using Yanfly's FTB system - and I'm wondering if there's a way to make sure an enemy uses a skill as soon as it meets the prerequisites. In my case, I'm making an enemy's MP rise over the course of the battle, and having it cast a spell once it's at 100% MP. However, the enemy sits at 100% MP for one turn, uses a standard action, and the next turn, uses the 100% MP skill (if it can).

It looks like whether enemies can use a skill or not is evaluated as soon as the new turn begins, so if the enemy hits 100% MP during the player's actions (say, from the player hitting it with an enemy restoring skill) it doesn't know to use a different skill when its own turn comes around. Is there either a way to force it to reconsider its actions before it acts, or a script that allows it to interrupt and cast something immediately once it meets the parameters?

Thanks :D

Yea, I was trying something like that earlier. It looks like enemy actions are chosen in Battler_Base - The line looks like "$game_troop.make_actions" (something like that, I'm at work atm) and it tells every enemy to determine their action at the beginning of a new turn. I've been playing with it but I'm not sure where I can put it so each enemy determines their actions right before they act (or the whole troop decides when the players are done acting) - and I'm not sure if Yanfly's FTB messes with that at all.
