[Plugin: WordPress SEO by Yoast] How to add KML or additional sitemaps to wpseo sitemaps?

Hi!

HOW can I add to WPSEO sitemap functionality?

Specifically, I have location.kml and geo-sitemap.xml that points to it.

HOW can I add this to the list of sitemaps WPSEO manages?

Please, advise. Thank you.
