Sitemap/SEO Plugin and Google Webmaster Tools

Traditionally you can register your sitemap to Google through their "webmaster tools" system which gives you a lot of interesting insights about ranking etc. My question is; when it asks me for the xml sitemap location do I provide the direct link to the wp-conent/sitemaps.php file? I assume that's the way to do it since there isn't a sitemaps.xml file in the root of the site (or at least not yet). Thanks!
