I have found instructions for adding custom dispatch handlers into a phoenix application.
https://hexdocs.pm/phoenix/Phoenix.Endpoint.CowboyHandler.html#module-custom-dispatch-options
Now that phoenix supports cowboy 2.0 is there a way to do this for cowboy 2.0. Specifically I want to add some custom handlers that are cowboy stream handlers.
https://ninenines.eu/docs/en/cowboy/2.0/guide/streams/
This might be a question more for the phoenix team. @chrismccord or perhaps @Gazler?
