Can epic start and end date linked to its child issues' start date and end date in Roadmap?

Question

Like portfolio, the epic's date is correlated to its child issues' dates.

For example, if I set an epic with 2 child issues:

Issue A which starts and is done in sprint 1 (11/28/2018 - 12/3/2018)

Issue B which starts in sprint 1 and is done in sprint 2 (12/4/2018 - 12/10/2018)

In the Roadmap, can the epic start date be automatically updated as 11/28/2018 and end date as 12/10/2018, instead of changing manually?

As Bryan eluded, natively this is not the way it works. I raised this to Jason Wong (cloud PM) in the recent AMA he created. I provided a bit of feedback on how it should work. I have not opened a suggestion and unsure if anyone has as yet. If so inclined you may wish to research this on JAC

In theory you can use ScriptRunner to achieve this behaviour by utilizing the listener feature.

I may be wrong but I think there is some sort of built in automation under the hood of epic but I haven't really looked into it.

Every time an issue is created, the due date has been updated and issue has been linked to the epic it will trigger the psuedo-code in order.

* Find the issue
* Find the epic of the issue
* Find the issues linked to the epic
* Collect the due dates from all the issues inside the epic
* Calculate the earliest due date and the latest due date
* The result will determine the start date and the due date of the epic
* Update the start date and the due date of an epic
* Win!

That being said, there might be an add-on to implement this but its just a rough idea.
