Is there a way to modify the smartsection, articles2 and ams plugins for sitemap module to show not only the categories but also the articles under each category in the sitemap module. I ask this as i intend to use the sitemap module only for google webmaster tools purpose. It will be better if i can submit all my articles as a part of the sitemap.

Also how to modify the plugins to ensure that seo urls are shown in the sitemap when url .htaccess rewrite is used instead of the old urls?
