Set a variable in AngularJS to contain several declared variables

Is there a way to combine multiple variables into one variable in order to streamline code usage? How can I set it up so that I can utilize $scope.bundle instead of using $scope.acc.city, $scope.acc.state, and $scope.acc.country individually? I'm looking for a global variable that consolidates multiple variables for easy access without the need to repeatedly declare them.

This is how I envision it:

$scope.bundle = [{$scope.acc.city, $scope.acc.state, $scope.acc.country}]; 

$scope.postcode = resp.content;
if ($scope.postcode.length > 0) {
   $scope.bundle = $scope.postcode[0];
   $scope.acc = $scope.bundle;
} else {
   $scope.bundle = '';
   $scope.acc = $scope.bundle;
}

Instead of this:

if ($scope.postcode.length > 0) {
   var data = $scope.postcode[0];
   $scope.acc.city = data.city;
   $scope.acc.state = data.state;
   $scope.acc.country = data.country;
} else {
   $scope.acc.city = '';
   $scope.acc.state = '';
   $scope.acc.country = '';
}

To store multiple objects in an array, it is important to assign unique keys to each set of values

$scope.bundle = [
   {
       city    : $scope.acc.city, 
       state   : $scope.acc.state, 
       country : $scope.acc.country
   }
]; 

This allows you to retrieve specific values using their assigned keys

$scope.bundle[0].city 

If you only have one item (instead of an array), you can create the object directly without the need for indexing

$scope.bundle = {
    city    : $scope.acc.city, 
    state   : $scope.acc.state, 
    country : $scope.acc.country
};

This way, you can access the values directly without specifying an index

 $scope.bundle.city
