WooCommerce

It would be great if there was a way to easily identify new customers to our store. Currently we would print the invoices and packing slips for our orders. We then manually search in the orders database to see if this customer has ordered with us before, or if they are a new customer. New customers are then identified so we can include specific leaflets, product scoops etc. If there was a way for the invoices or even just the orders page to identify a first-time customer, that would be very helpful. That is a feature that a lot of people would pay for. Thanks.
