Angular complex routing, multiple parameters

So im currently trying to figure out the best way to work with multiple routes in angular. So for example I have this in my app.js:

myApp.config(['$routeProvider', function($routeProvider) {
  $routeProvider.
  when('/list/:1/:2/:3/:4/:5', {
    templateUrl: 'partials/list.html',
    controller: 'CustomCtrl'
  }).
  when('/details/:itemId', {
    templateUrl: 'partials/details.html',
    controller: 'DetailCtrl'
  }).
  otherwise({
    redirectTo: '/list',
    templateUrl: 'partials/list.html',
    controller: 'ListCtrl'
  });
}]);

Currently the application I am making can have UP TO 5 different parameters within the URL. (As seen above ex: www.example.com/#/list/1/2/3/4/5)

My question is when ONE (or any amount) of those parameters are missing let's say 4 (ex: www.example.com/#/list/1/2/3/5) it defaults to my regular 'ListCtrl'. Is there a possible way in angular to say.. Well even though parameter 4 isn't available I'll still goto your 'CustomCtrl' because I see that indeed some parameters are listed.

Or should I be coding this a completly different way all together? Thanks for the help!
