FYI, Flowsana includes this feature: you can set a dependent task B which is dependent on task A, and enter into an “Assign To” custom field the person to whom task B should be assigned.
Then when you mark task A as complete, task B will be automatically assigned an appropriate start and due date and it will be automatically assigned to the person you identified.
If interested, you can read more in this forum post.
