While a dedicated nixos option might be nice, you do not need one to accomplish your goals here.

The services.tor.settings set follows RFC 42 so you are able to specify the MapAddress option like so:

  services.tor = {
    enable = true;
    settings = {
      MapAddress = [
        "Test.com 2.2.2.2"
      ];
    };
  };

You can then check the generated torrc and should see something like this:

MapAddress Test.com 2.2.2.2

An option would be nicer and can add some type checking, but not having one shouldn't be a blocking obstacle on this.
