Well as I see this idea in my head, the items will also be stacked inside of a set if they get placed in one.

No matter what, any amount of chronos grips you have, lets say 3, will show up as Chronos grip (x3) no matter where it is in your inventory. If you press activate, it will remove one from the stack and throw it in your activated, if it gets deactivated, it will add it back to the stack. If you decide to send one of them, it will show up as Chronos grip (x3) in the transfer items page, click it to send it and a box will show up with an amount field. ("Amount to send:").

Very self explanitory and almost any problem you can think of can obviously be solved in minutes. I can't see anything wrong with this idea.
