[Plugin: Google Maps Store Locator for WordPress] CSV upload

I played with this plugin a while back and am in the process of installing it for customer. Is there a way to import a populated csv or tab-delimited file so that I won’t have to manually enter in a few hundred stores? Looks like support for this plugin is extinct and so is the upgrade site.
