MarketPress Product Question

Is there a way to have "item(s) added" displayed site-wide for an item once it is added to the shopping cart.

Example -

On your demo page
http://digitaldownloads.wp-ecommerce.org/store/products/classical-collection/

I would like to display "item(s) added" after the collection has been added to the cart. I would like that message to be displayed after refreshing the page. Essentially it would let the customer know that that item has already been added to the cart.
