Hapi.js Content Negotiation

I want to do content negotiation in my hapi routes to I can return the type of data my client can accept.

With express I would do somthing like this

res.format({
  "text/plain": function(){
    res.send("Text Response");
  },

  "text/html": function(){
    res.send("HTML Response");
  },

  "application/json": function(){
    res.json({ message: "JSON Response" });
  },

  "default": function() {
    // log the request and respond with 406
    res.status(406).send("Not Acceptable");
  }
});

Is there a built in way to do this with hapi? I looked through the API docs and didn't see anything. Am I stuck rolling my own solution?
