Drop all same mag / ammo

[rz22g 10]

Is there a mod that will allow you to drop all ammo of the same type at once? For example in backpack there are 5 45 mags, 3 9mm mags, 6 revolver cylinders. You would normally have to right click on the 45 mags 5 times to get rid of them all. It would nice to have a modifier key, for example hold a certain key while you right click once and it drops all of the type you clicked on.
