I would like my Jira Board to send out a repeating email notification based on the subscription I've created. Ex: I want the email to go out 60 days prior to the estimated End Date of the Sprint. I can count the days, and manually put in a calendar date that meets that requirement, but what if the Estimated Completion Date for the sprint changes? Is there a way to have that subscription automatically adjust itself to the new date, without having an admin going in to change the subscription dates for each? Thanks in advance!
