Feng Office allows assigning a single task to different users! Even though subscribing users could be useful, this would not be as good as being able to properly filter tasks per assignee as then the people would rely on each other and no actual responsibility may be taken for the task per se.

The subtask will have the same description, start date and due date than the main task, and by default the same estimated time as well.
