Adding custom routing

[twaclaw]

Hi,
Is it possible to add custom routing? For example, could I add tools that are called once before calling the supervisor or after the supervisor produces the final answer?

I can do that when manually creating a supervisor with a create_handoff_tool but don't know how to do it when using create_supervisor.

For instance, in the following graph, how can wire date_to_prompt and formatter to the supervisor created with create_supervisor?

Thanks in advance.
