Is there a way to restrict the number of associated items that are displayed? I have Better Together with Checkout Candy with the buy it now button.

For example if I set up item A to have items B, C, D, E, and F associated with it, and I add item A to my cart, all five associated items will show in my shopping cart. Is there a way to only have two randomly show from the list of B, C, D, E, and F?
