Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
Unfortunately, Rank Math does not have the option to merge the sitemaps from your multisite installation.
However, if you wish to add the extra custom sitemap and other customization, please refer to this guide: https://rankmath.com/kb/filters-hooks-api-developer/#add-extra-urls-in-sitemap
Hope that helps.
Thank you.
