Paying to view directory listings

I'm in the process of setting up a website and *think* that I may need to combine your directory & members plugin. I see that you have the option in the directory plugin to charge for listings, however, I want the listings to be free - but want to be able to charge to view the listings. Is this possible with the directory plugin alone, or is there a way to use both the directory & members plugin to make this possible? Thanks!
