This would be helpful.
I especially need it to insert expiration dates in subitems based on the date of the parent item.
For example, the first subitem must be done 10 days before the parent item expires, the second 8 days before, etc.
Is it possible to flip this? I would like to reference a subitem in the parent item. Specifically, I have a list of tasks with dates, and I would like to have a column in the parent item that shows the “next” date in the subtask list.
