Exclude specific sites/articles from sitemap

Hi,

is it possible to exclude specific sites/articles from the sitemap with Infinite SEO?

Example: If I don't want Google to index my imprint or privacy policy site, I set meta robots tag "noindex" for it and therefore I don't want this site to be part of my sitemap.

Is it useful from the SEO-perspective? How can I make this happen?

Best regards,
Ilias
