I seek help and guidance implementing an equivalent of Etrian Odyssey's bind system in my game!

In case you are wondering, EO replaces the silence state with binds. Ex. head bind seals skills that use the head, mouth, eyes, etc.
[Here's a more detailed description: http://etrian.wikia.com/wiki/Bind]

I thought that I could try to simulate it with a state like Silence but instead of sealing magic it seals one of the three types of skills in the game. So, I met a wall when I found that in the menu that skills would be separated in sections, and I don't like how it looks. It makes the menu list innecesarily long.

Is there a way to work around this? Have all three type of skills in just one section? Or make all the skills the same type and use notetags to seal certain skills when bound, and if so which tag (I'm kinda new in all of that)? Plugins? Something outside the box I havn't thought about?

Any advice helps! Thanks for your time and attention.
