Pass custom fuzzy match into replayweb.page

I was looking at the documentation for embedding replayweb and saw that the “config” attribute is available when using <replay-web-page>. I know there is a way to pass in site-specific URL fuzzy match configurations using this attribute. Is there currently a way to pass the same config to the live https://replayweb.page service or is this option only available when using embedding at the moment?
