I have a shopping cart module where a number of related products are being displayed in the product details page. However, I would like to display related products section in the cart checkout page as well. Currently, if there are more than one related products connected with a product, all the related products show up below the cart section. We want to display only one related product here. Please check attached image. There are 3 products in cart, first & second product has one related product and 3rd product has multiple related products. We want to display only one related product for 3rd product i.e. one for 1st, one for 2nd and one for 3rd product.
