Free Shipping on orders including specific products

I am trying to build free shipping into my store, but only on orders that include specific products. 

I was able to create free shipping for those specific products, however when any extra products are added to the cart, they are charged shipping still. 

My goal is to make a profile that contains conditional free shipping IF specific products are added to the cart. Is this possible? If so, how?
