Redirect "add to cart" button on dummy product that redirects to bundle (when clicking on image)

[Totalmann]

Hi, 

I have created a dummy product that is in my featured collection on my home page that redirects (when clicking on image) to an bundle that I made in Bundler app. However, the "add to cart" button (marked in red below) adds the dummy product to the basket/cart and thereby leaving the inventory count wrong. Is there a way to redirect this button so it adds the actual bundle to the cart and thereby deducting the inventory correctly? 

What I really want is to add the actual bundle to the collection, instead of the dummy, but as I understand that is not possible. 

I am using the "Refresh" theme.

If you have an solution, please explain it in detail, as I am new to coding, thanks 😄
