Hi @anon42353856, thanks for reaching out! As it stands, it’s currently not possible to automatically add subtasks to tasks created via a form submission. I believe there is a workaround with Flowsana, you can see more details and upvote for this feature in this existing thread: Forms: Ability to have questions trigger a task/subtask creation & option to share/manipulate at form level - #7 by Phil_Seeman
