We integrate with Jira Engineering work at the Requirement level and must see dates associated with Jira Stories as Requirements in Aha! Since addressing the Requirements / Jira User Stories make our Features a reality, we request that a setting be put in place in Aha! to allow Requirement dates that roll up to a Feature to drive that Feature's start & due date.
Thank you for your idea. We would recommend adding custom date fields to capture dates on your requirements. You could then map these to the appropriate Jira fields to create visibility within Aha! as to the dates added by engineering.
At this time we are unlikely to add automation to the way the feature due dates are calculated. We hope you can understand.
