Uh, wait I am confused as to what you are trying to suggest. You want the item text (the name of the item) in the store window to be changed? Is that it?

If that's not it, then I don't understand, unless you are saying you want something to display an item you already have? If that's so, we already have that, that Qty. (Quantity) on the side will display a 0 if you don't have the item in your inventory or armory chest, and a 1 if you do.
