Product Variations in MarketPress

Is it possible to do multiple product variations? I can clearly see where to add the options in the product editor, but it looks to only suport one variation, like color. I need size, color, shape, and finish all on one product? Other e-commerce plugins call it attributes and variations. Is it possible with marketpress

Also just as a said note, if you stick to one variation, but add a different price for each, when they're added to the shopping cart the price doesn't calculate correctly.
