TL;DR: When a subitem is created, automatically set its date to today + a fixed offset. Useful for SLA-based workflows where every task is due X days after it was added — independent of the parent item's date.
What this does
The subitem's date is set to its creation date plus a fixed offset. The same offset applies to every new subitem on the board.
Example: every new subitem gets a Due Date 5 days after it was created.
When to use it
SLA-based workflows (every task due in X days from creation)
Support tickets, customer requests, inbound work
Due dates relative to when the task was added, not project start
Workflows where there's no meaningful parent date to anchor to

Test that it works
Create a new subitem on the board.
Confirm its Due Date = today + 5 days.
Common gotchas
Fires for every new subitem. If different task types need different timings, use the by-task-name variant instead.
Date column must exist on the subitem. If it doesn't, the automation has nothing to set.
Use negative numbers for dates BEFORE creation. Rare but possible — e.g. "due yesterday" workflows for backdated entries.
