Is it possible to add an item's manufacturer to a receipt, in addition to the other default information?

{ADD THIS} Manufacturer: ACME
------------------------------------------------------
I have 13 manufacturers in my store. When I receive an email receipt for each order, I forward it to the manufacturer which handles the fulfillment.

However, this is such a repetitive task, and I figured I could use Gmail to my advantage.

A gmail filter could look for text such as "Manufactured by: ACME, Inc," and upon receipt, take the necessary action. (In this case, "if BODY contains Manufactured by ACME, send email to [email protected]")

So, in summary, is there a way I can include other information in my email receipts?
