如何创建一个按钮来选择Magento 1.9中捆绑选项中的所有“无”值?

I want to have two buttons for bundle products just under pricing, "Buy Barebone" "Add to cart".
By clicking on Add to cart button it should simply add all the pre-selected bundle options to the cart. However, clicking on Buy Barebone should select all 'none' values available in all the bundle options.

This would allow the user to buy either just single primary product or add/remove other components.
