Can Tahm Kench please prioritize eating the enemy?!

I was recently playing Tahm Kench and while an impressive tank, his Devour ability was the most disruptive pain I could imagine. I would attack the enemy and get three stacks on him and run in to devour but that useless ability would eat ANYTHING ELSE POSSIBLE before it would devour what i clicked. What does this ability have against devouring the enemy champions? In the middle of a teamfight you charge in with the sole purpose of getting three stacks on the enemy damage and taking them out of the fight for a few seconds, and when you get the stacks the skill prioritizes EVERYTHING ELSE! Can we please, please PLEASE set this skill to prioritize devouring an enemy with three stacks when all the champs are piled close together? Please?! I promise that if I get three stacks on someone my intention is absolutely to devour that person and went out of my way to make it possible! Not minions, and certainly not to eat an allied champ and take his damage out of the teamfight!
