Different send to email depending on form


Is there a way to customize the DH forms to have a user select from a drop down what their interest is, then depending on that choice - the form information will be sent to a specific email address?

For example, a user visits and would like to know how to purchase a few of a product - that email would go to our retail sales person. If the person would like to purchase in bulk, that email would go to our warehouse.

Make sense? Hope so, now how to do it?
