Hideable Bars?

[HeroFromHyrule]

I'm wondering if there is a way to hide a bar that has things on it? I want to setup my hotbars for my Hunter so I can have Aimed Shot while not in combat, and then have it switch to Disengage while in combat. I've already changed the IDs and all of that, but I want to know if I can hide the bar that contains disengage so that I don't just have it floating around? Is this possible?
