$ionicConfigProvider nav button icons

For the tabs, I use this to change the icons for both platforms:

  .state('app', {
url: "/app",
abstract: true,
templateUrl: function() {
  if (ionic.Platform.isAndroid()) {
    return "templates/tabs-android.html";
  return "templates/tabs.html";


I know you can change the backButton.icon(value) icon. Is there a way to do this with $ionicConfigProvider for nav button icons or just icons in general.

I found just found this and I thought I share: https://github.com/antonshevchenko/ionic-contrib-icon
