Python: Bug: [python] ProcessEdgeBuilder cannot send events to steps with multiple functions #10340

ProcessEdgeBuilder cannot send events to steps with multiple functions

Description

Kicking off a kernel process with process.on_input_event(SomeEvent).send_process_to(MultiFunctionStep, function_name="some_function") results in KernelException: The target step has more than one function, so a function name must be provided.

Reproduction

MWE

Expected Behavior

I expect to be able to route to steps with multiple functions on a ProcessBuilder.on_input_event in the same way that I can from a ProcessStepBuilder.on_input_event.
