Can I make Combo products in Marketpress?



I am understanding Marketpress for the most part, But I am building an Online Store and have Single products with no issues. Is there a way to build a Combo item without having to make it an individual product? For instance… I have 1 DVD and 1 T-Shirt, they are marked for x price individually but i want to offer a y price if they are bought together. Kind of like the combo purchasing Amazon does, but i want to offer it not make it auto add.
