Are multiple shipping options possible in MarketPress?

I'm setting up an online store that will accompany a brink-and-mortar antique store. Some users will buy items and want them shipped, but others will want to buy them and then pick them up in the store. Under shipping I have set it up for calculated. Is there a way that will allow users to select "pick up in store" or something which would leave the shipping column as $0.00?
