Issue:

Sometimes you might want to alter the behavior of a route controller. By default, a controller can only be exchanged once by altering the route and replacing the route controller.

Solution:

Use the provided snippet to simulate a decorator pattern for an existing controller like you would do with services. This enables you to alter the outcome multiple times.
