Add Divider

The purpose of the Divider is to help distinguish (visually) several product lines to identify them in a group. When creating the quote, The admin can see the divider as a space between product lines. However, from the customer's perspective, each Divider appears as an additional product line in the quote/order/invoice. Can this feature be modified so the space can just be a space (in the pdf/printable format), without it having to be another product line?
