Can you implement the WithChannel Feature ?

[Xsmael]

Can you implement the WithChannel Feature that allows you to get the channel on wich the message was sent in case you subscribe to multiple channels like so:

client.subscribe('/foo/*').withChannel(function(channel, message) {
  // handle message
});
