I need trigger help

How do you make it so you use a multi-use item all at once. cuz im making a map with a tome x1000 and i want to make it so you only have to click once instead oof 1000 times but still have 1000 charges

Not necessary a trigger, but change the item ability to 1000 in object editor, ability sub-cat, on the item ability group.
