If you need to add extra subtasks to a specific task - ones that are not part of the original task template - you can do this directly from the task panel. These are called Additional Subtasks and they apply to that one task only.
Adding an additional subtask
Open any task and scroll down to the Additional Subtasks section.
Click the '+' button to add a new subtask, then type out the subtask
Press Enter to save it.
Managing your subtasks
Once added, you can:
Mark it complete - tick the checkbox next to the subtask
Edit the name - double-click the text to edit it
Reorder - drag subtasks up or down to change the order
Delete - click the bin icon to remove a subtask
These only affect this task
Additional Subtasks are limited to the individual task you add them to. They do not change the template the task was created from, and they do not appear on any other tasks - even other tasks created from the same template.
If a task already has subtasks from the template, those appear in a separate Subtasks section above. Your additional subtasks sit below in their own clearly labelled section.
Note: You can add additional subtasks if you are an admin, the person assigned to the task, or the person who created it.
Activity Log
Any additions, edits, or removals of subtasks are tracked and logged in the Comments & History menu on the task.
You can view a full history of all subtask changes alongside other task activity by opening Activity on the right-hand side of the task.
