How to List Pack of Products Individually in the Invoice under Prduct Name

[Precision_Sam]

I have a product (e.g. name:  complete_Set_of_Three) which is a pack of 3 different individual products (itemA, itemB, itemC).

I would like to display all 3 individual products in the invoice under the product name.

In the file invoice.product-tab.tpl, I'd like to have {$order_detail.product_name} to show:

complete_Set_of_Three

  [itemA] x 2

  [itemB] x 5

  [itemC] x 3

How can I modify the HTMLTemplateInvoice.php?  Thank you very much!
