I would like to see the functionality beyond just sub task dependency. There is no reason to limit the functionality of regular tasks as well. Let this be a linkable thing across all tasks.
Ideally I could build a template based off the project due date or some other master date that would distribute scaled dates from there.
I had this functionality in a google sheets we used to use for milestone tracking and this is sorely missed. I empathize with others here on the tediousness of date management.
