Reporting on Closed Won Deals with Multiple Companies

Hello,

We often have two companies associated to a Deal. The Company that Purchased and the Partner that brought us the lead. I need to run a closed won report that will show me both companies associated with a closed won deal. I have not found a way to do this without showing multiple lines for the same deal. I would like the company column to just list both companies. What is the purpose of adding an association label to Companies>Deals if you can’t report on it / action it in any way? Seems like a no-brainer.
