Transfer favorite communities between accounts? - eviltoast

Is it possible to transfer favorite communities from an account on one server to another? Say for example I’d like to have an alt with the same favorites on another server for a backup. Is this possible with wefwef or other means?

Looking to get my main off lemmy.world to help load balance, but I don’t want to refavorite everything; if I could somehow keep them in sync that would be ideal.
