The idea is when you have a piece of equipment selected, for instance, ammo, if you hold a key down (Alt?) and click to place the item in a slot, another of that same items gets placed into the cursor holder. This would allow for rapid placement of items on an agent. If there are no more of the item, then nothing happens after it gets placed. There could potentially be the quantity of that item left next to its icon so the player would more easily be able to see how many are left. This could be an alternative to making multiple templates for minor changes.
