custom link for xml sitemap

Hi, I really think this is very important, as the onsite-check might be missing urls without this.

In my case this is exactly what happens as i have compared the results with other crawling tools.

So a formfield to set the url of one or many XMLsitemap URLs for the onpage check crawling would be very important. (competoitors have this as well)

Without this, the onpage check could give a false impression that everything is fine. Instead many urls from the sitemap might having issues and are not detected right now.

thanks!
