Sorry to necro, but if anyone else is seeing this or if you haven't done it there is an option in the standard CE tables (under Underrail AOB script; main) to edit the inventory item your mouse is currently hovering. You'll be able to change the item ID from whatever it is to the desired item. Bit fiddly though, I've tried it many times but only gotten it to work once. Enough to verify it does indeed work though.
