AngularJS dynamic routing

I currently have an AngularJS application with routing built in. It works and everything is ok.

My app.js file looks like this:

angular.module('myapp', ['myapp.filters', 'myapp.services', 'myapp.directives']).
  config(['$routeProvider', function ($routeProvider) {
      $routeProvider.when('/', { templateUrl: '/pages/home.html', controller: HomeController });
      $routeProvider.when('/about', { templateUrl: '/pages/about.html', controller: AboutController });
      $routeProvider.when('/privacy', { templateUrl: '/pages/privacy.html', controller: AboutController });
      $routeProvider.when('/terms', { templateUrl: '/pages/terms.html', controller: AboutController });
      $routeProvider.otherwise({ redirectTo: '/' });
  }]);

My app has a CMS built in where you can copy and add new html files within the /pages directory.

I would like to still go through the routing provider though even for the new dynamically added files.

In an ideal world the routing pattern would be:

$routeProvider.when('/pagename', { templateUrl: '/pages/pagename.html', controller: CMSController });

So if my new page name was "contact.html" I would like angular to pick up "/contact" and redirect to "/pages/contact.html".

Is this even possible?! and if so how?!

Update

I now have this in my routing config:

$routeProvider.when('/page/:name', { templateUrl: '/pages/home.html', controller: CMSController })

and in my CMSController:

function CMSController($scope, $route, $routeParams) {
    $route.current.templateUrl = '/pages/' + $routeParams.name + ".html";
    alert($route.current.templateUrl);
}
CMSController.$inject = ['$scope', '$route', '$routeParams'];

This sets the current templateUrl to the right value.

However I would now like to change the
