How to set the key name on an array in Angularfire

Question

I am creating arrays using Angularfire but I am unable to set the key name. Firebase is automatically giving me a cryptic key (eg Jm9vLy8Lye-KS35KsmL) but I would like to set it myself to something more meaningful. It is unclear how I do this in Angularfire. I am using the $add method on $firebaseArray:

var firebaseRef = new Firebase("https://firebase_location"); 
$scope.messages = $firebaseArray(firebaseRef);

$scope.messages.$add( 
  {
    FirstName: patient.FirstName, 
    LastName: patient.LastName
  }
).then(function(firebaseRef) {
  var id = firebaseRef.key();
});

The data is stored fine and I can see it on my dashboard. However, id is always a cryptic firebase value. I would love to be able to set it myself to something meaningful. In my case the individual patient's ID would be meaningful...

Any thoughts?

Thank you!

Thanks for the response.

I found that the child function will do what I need. I first specify the child and then set it.

var patient_child = firebaseScreenRef.child(patient.PatientId); 
      patient_child.set(
        { 
            FirstName: patient.FirstName, 
            LastName: patient.LastName, 
        });
