Looking to have the person assigned to a parent task also assigned to all of the subtask s of the same task.
The last sections do this is set to user assigned to trigger task.

Rules can’t target subtasks (yet). They can create the subtasks, but not do anything to existing ones.
FYI you can accomplish this with the upcoming update to our Flowsana integration. It’s just going into beta; you can email us at support@flowsana.net if you’d like more information.
