Hi guys,
What I want to do is:
When Delivery Date (custom field) of a Story changes, all Delivery Dates of subtasks under that Story need to be copied.
The automation rule looks like this:

And In Edit, I want to use "Copy from trigger issue" for Delivery Date just like Priority, but it does not have dropdown options.
I figured out that Priority works fine with "Copy from trigger issue" option, but I am not sure how to select it for Delivery Date.
