Wordpress Ecommerce CSV Generation Customization

General Overview: I have setup a client's website using wordpress. I have also installed the wordpress e-commerce plugin by (<[login to view URL]>). Currently the cart will generate a sale report in the form of a csv file. I need to customized the information that is exported to csv. Specific Requirements: The cart is being used to sell concert tickets. A typical show for this music venue will sell around 1000 tickets. The client has requested that they be able to select a particular concert or "product" and have the cart generate a csv file that lists: first name, last name, and qty purchased **for that product only**. This list is being used as a "will-call" list at the front door of the club. Basically it would be a "per product" sales report. I hope this makes sense. Please email me if you have any questions or need clarification.
