Hello,
Thanks for getting in touch with us.
We are sorry but we do not have any options to do that.
What you can do instead is create a new XML sitemap and use it as a index. Create it manually and include all the XMLs sitemaps from Rank Math and include your own in there as well.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
