Can I add a cross sell/bundle where if you buy one product you get the other for free?

I have Alidropship woo but when I add cross sells to a product it just shows up next to it in the shopping cart as if it were an upsell. Can i not create a bundle using cross sells to make another product discounted or free with the purchase of a main product?
Did yu ever figure out a way to do that? Im wanting to create BOGO's and quantity bundle packs
