MarketPress checkout pages

I have MarketPress installed and running. It works great, but I have a problem using it with the work I do.
I would like to know is there a way that I can add a note or comment form in the checkout pages. Sometimes my customers need to add notes how to handle the product and I need a way for there to send me a comment or note when they are checking out. Can I add a comment field on the page that say Your Shopping cart and it show whats in your shopping cart like:

Item: Price: Quantity: note or comment

If not like this is there something close
