I am trying to figure out how I can use different invoice designs for different types of products. For example, I would like to sell a product offered by another department in our organization, but the contact information and logo need to be different.

I was thinking about creating a new order_invoice.tpl file with a new name that would use a different logo and contact information. But I am unsure how to call this invoice template for a specific product purchase. Perhaps it is called for all products in a specific category? Any help would be most appreciated! Thanks!
