I see this has been floating around as a “we’ll get to it” for a couple of years now, but I’m just pitching in on this…
The subitem automation is flawed until you can set a due date on the subitems based on the current date and/or the due date of the parent item.
I have an automation set up to create multiple subitems based on the type of project being added.
Each subitem should have the same due date as the project itself. Currently, there doesn’t seem to be a way to set the due date to anything except a fixed date that is always the same date regardless of when the automation runs (which seems like a bug).
I was fine just leaving the subitem date field blank, but if you do that, the reporting tool on team member capacity no longer works, as it’s looking for due dates.
Can we Automations on Sub Items with a Due Date Column ? I currently see only Status Column
Hey @rajaramans,
Can you specify the specific automation you’re interested in setting up? 
I want a similar automation based on Due Date for Sub Items since they are sub tasks for the main task. The Automation on Main Task works.
Issue with Sub Items Automation. You don’t find the Due Date only Status is available.

Is this the recipe you’re looking for? You should be able to choose the subitem due date via our custom automations:
Let me know!
Hey all,
We developed an app that solves this exact pain point of subitems inherting column value from parent and allows you to set sub item due dates based on its parent item date.
On creation - Populate item’s data into its subitems in a seamless way
On change - Being able to set dependency between a subitem to an item
There are also more advanced options with offset of dates -
It’s brand new (released last week) and we’re going to keep on adding new capabilities.

Hope that helps!
