SugarCRM Products has no Sub-Panel

I created开发者_StackOverflow中文版 a relationship between a custom module and products which seems to work. The only problem is, I want to list the products on the custom module as a sub panel but Products does not have a sub panel. Any way to create this?

My best bet is that you might have created a relationship that doesn't create a subpanel on the desired module end. For example 1-N contacts-products, in this case products won't have a subpanel but only relate field since there can only be one contact associated with a product.
