Change map name or location

Howdy! First time trying the plugin and ran into very minor thing. Our newsroom is in sub folder e.g.,

site.ooo/news

but then we also have all our services in

site.ooo

so, with the two installs of WordPress, the file overwrites one another. An option to set a filename, or root path for writing would be super useful.

e.g.,

Set relative path /root/news/image-sitemap.xml

Thanks! ??
