Set items to not print (show up) on SO, Invoice, Pick, and Packing Lists

SOLVED

We want to know if there is a way to set certain line items in an sales order to not print on any forms. We want to do this to track packaging materials used to fullfill an order. We clearly do not want to have the packing used to show up on invoices, sales orders, and packing/picking lists. 

We also want to do this to track other components used to fullfill an order so we have a better idea of profit per order. These items will have a $0.00 amount on the SO. 

Does anyone know of a way to do this? Certain items can be sold both as a finished good, or as a component, so making changes in item maintenance will not help.
