If you create tasks or subtasks automatically, you can already copy the task name and the description of the task that triggered the automation. But not the priority, start and due dates, user-defined fields and the person responsible. I constantly stumble over this missing automation function and therefore cannot create the automated tasks properly. If you use a task as a trigger to create another task, it is usually also necessary to set a relationship to the corresponding task. You can set a relationship if you create it as a user-defined field, but again not with the function to automatically connect it to the task that triggered it.
