Include Data for "Account Number" / "Company Code" in each Print Order

[barrytarter]

@jlnmay as part of each order, we'd like to include our company discount code in to the order.

Basically our account number, aka company discount code is 0328409496 and we'd like this applied to each order -- it can be a static value sent along with each order as we don't change it. Can you add this into the submission process for the order?

If you can't determine the API variable from the documentation they shared, lmk and I'll ask Bob.
