Gear Set Tweak

Would it be very difficult to put in an option to NOT show (breakable) items used in other sets when using other gear sets? Perhaps a toggle button to show/not show?

I want to set up the same formation using different items...so I don't want overlap. It is possible without this feature, but it makes it difficult when you have items breaking nearly every battle.

E.g. I set up formation 1, when setting up formation 2-4 I don't want any overlap (except unbreakable items). Also, when an item breaks, I don't want to replace it with something that is being used by another formation.

I'd also want this for heroes' items.

Thanks.
