Accessing "Step" option from the Ansible API 2.0

Hello list!

Using the Ansible API 2.x what would be the easiest way to pass the “–step” option to the PlaybookExecutor call?

eg from:

PlaybookExecutor(playbooks=playbooks, inventory=inventory,
variable_manager=variable_manager, loader=loader,
options=options, passwords=passwords)

I’m using Ansible 2.2.0.

Thanks

So apparently the way to achieve this is via a Strategy plugin.

eg https://github.com/ansible/ansible/blob/9694d60af5e9cde7aa684e9795b79f9fbb928ce5/lib/ansible/plugins/strategy/debug.py

What’s the best way to associate that plugin type with the PlaybookExecutor object?
