How can I use the Reports to show Products attached to Accounts & Potentials in the CRM?

I'd like to be able to report on the Accounts and Potentials in our system and show what Products are attached to each. When the 'Products' sync to the Reports module, it is just a table of the products entered, non-relational. The Accounts and Potentials tables also have no relational field to Products.
