Yes, I do have an advanced search option to those who have purchased a Pro Pack and request it while their license is active. You can see it in action on this third part site:
This site does not show the country option, but there is one that can be enabled. After choosing a country, another drop down will populate the state choices. The choices for both populate from actual entries addresses in the directory.
I consider this beta software, though safe to run on live sites. I offer installation and configuration as a service for a fee due to it have a somewhat complex shortcode setup. If you are familiar with shortcodes it should not be too difficult. They styling is as is, though I can give you CSS to apply you own color (instead of blue).
I hope I have answered your question thoroughly!
