Template editing question

Template editing question

I am attempting to utilize the default "Sales Order" template to create a packing list template.  Is there a way to edit the "Product Details" section in this template?

Currently it displays: Product Name - Product Code - Qty - List Price - Total

I would like to display: Product Name - Product Code - Qty Ordered - Qty Backordered - Qty Shipped

Is it possible to edit this area? 

Or is there a better solution?

Any help is very much appreciated.
