Custom invoices from marketpress?

I need to be able to generate a different invoice for each product. I am using Marketpress to sell a service, which is does well but tax laws are changing so I need to alter the invoice.

It would need to looks like

Product is 1 hour with John Smith, commission is standard on all products.

product ----- Qty ------ charge -------- Tax
John Smith ---1----------£100------------- 0

This possible?
