Marketpress Create New Product - can I add a label to the product description box?

On the Create New Product input screen, the product title has a grey label saying "Enter Product title here" which disappears once the user clicks in the box and starts to type a title. Is it possible to have a similar label in the big box below saying something along the lines of "Add your product description here. Add an image by clicking set featured image in the Product Image box." ?
