Contact Form fields from database?

I am currently using contact form 7. In 3 of my contact forms, I need to put in a drop down box to select store location. This store location is saved in the database as well. I have not been able to find a plugin that lets me pull fields from the database, or even a hack where someone has done this. Is there a way that is easier than writing a whole new plugin from scratch to dynamically fill in these fields from the database rather than having to change the database, and all 3 forms? Thankyou.
