[Plugin: Gravity Forms Custom Post Types] How do I display custom taxonomy name rather than ID in

I am using Gravity Forms with the directory add-on to create a classified ads site. I have created a dropdown custom taxonomy selection in my Gravity Forms form and I would like to store the selection by name rather than ID number so that when site visitors see the directory list they see the selection name rather than an ambiguous number. How do I do this?

Thanks!
