Shipping Cost For Each Item

Does anyone know how to have an order/invoice display the shipping cost per item? I’m looking to have it display on the skins/admin/views/orders/details.tpl file.

Since I use a relatively advanced formula for calculating shipping based on the product weight I would like to be able to display the shipping costs per individual item on my order. I’m guessing that it would require a call to the shipping calculator for each item in an order since the order database table only stores the total shipping cost for the entire order.

Thanks in advance for the help.
