That a good suggestion mate but don't think it'll work. Ill explain what I'm doing

When an animal is killed, I have a script that removes all its items, and adds a new item, Carcass. Essentially changing its death item from hide etc to my item. This works great.
Player then crafts a pelt using the carcass. What I want is for the animals death items to them be added to the player. I can add an item easily, as I have an SM event set up already which runs a quest that updates a global.
I thought using AddItem for a levelled list might work, because you can AddItem a levelled item.
Any chance of me doing this? I think it's impossible to store the originally removed items somewhere as the player could kill numerous creatures before hitting the crafting station.
