I would like Webflow to be able to have different sitemaps for different collections.

Also, the autogenerated sitemap does not include the following XML file tags/attributes ...

priority
lastmod
changefreq

I see that I can upload my own sitemap, but it would be nice if Webflow generated it for me with these extra tags that could be set globally.
