AngularJS directive two way binding for a configurable number of variables

Question

When creating a directive, while defining isolate scope with two way binding using = is there any way that I can bind an array of scope variables. ie. if in my controller I have objects defined like $scope.one, $scope.two etc. and there can be any number of those - I want the directive to be able to handle a configurable number of them. How could I do that?

I can't do this, since another controller that uses the directive may have ten, so I want it to be flexible:

.directive("example", function () {
    return {
        scope: {
          one: "=",
          two: "=",
          three: "="
        },
    ...

Answer 1

Off course it is:

.directive('example', function() {
   return {
     scope: {
       config: '='
     },
     link: function(scope) {
       var firstOption = scope.config[0];
       var secondOption = scope.config[1];
       //...
     }
   }
}

The array options would have to be stored at a fixed index, so it would be less readable than passing a config object

.directive('example', function() {
       return {
         scope: {
           config: '='
         },
         link: function(scope) {
           var firstOption = scope.config.firstOption;
           var secondOption = scope.config.secondOption;
           //...
         }
       }
    }
