Custom sitemap URLs

On many occasions I see that YaCy ignores sitemap.xml from a site to be crawled.

When I paste the link to start of the crawler, it does not allow me to click on sitemap url.

I think this happens when robots.txt does not have a sitemap entry though the site has a sitemap_index.xml or sitemap.xml files

Another issue is that there are sites that contain multiple sitemap files, i.e.
Sitemap: https://www.cnn.gr/sitemap-news
Sitemap: https://www.cnn.gr/sitemap/articles
etc.

And yacy loads only the first one in such cases.

Is there a way to manually enforce one or more sitemap urls in these situations?

Thanks

I discovered I can use crawler API Dev:APICrawler – YaCyWiki and that solved all my problems
