我可以在Angularjs Material中的另一个'mdbottomsheet‘上打开'mdbottomsheet’吗？

angular.module('myApp', ['ngMaterial'])
  .controller('MyController', function($scope, $mdBottomSheet) {
    $scope.openBottomSheet = function() {
      $mdBottomSheet.show({
        templateUrl: 'bottomSheetTemplate.html',
        controller: 'AnotherBottomSheetController'
      });
    };
  })
  .controller('AnotherBottomSheetController', function($scope, $mdBottomSheet) {
    $scope.openAnotherBottomSheet = function() {
      $mdBottomSheet.show({
        templateUrl: 'anotherBottomSheetTemplate.html',
        controller: 'YetAnotherBottomSheetController'
      });
    };
  })
  .controller('YetAnotherBottomSheetController', function($scope) {
    // Controller logic for the yet another bottom sheet
  });
