Word Merge Document

We are buidling somthing like a shopping cart process that is writing selected items to a temporarray sql table. After the customer is done we wanted to generate a PDF that lists all the options they added to the cart. I can get the data out of sql easy enough. The problem is the only way I know to make a PDF in Workflow is by generating a word document with the word merge. But you cannot add the array to the word document only single entries so it can either list the first or last item from the sql results has anyone accomplished this? If this was crystal reports it would be easy but word just isnt as powerful.
