Regarding importing features into Aha! that are not part of a fixed version in Jira....Today, When you import these features, they will land in the left most active release. If there is not an active release, they will land in the left most parking lot release. In the scenario where there are active releases, and the JIRA object does not have a fixed release, it should flow into the Parking lot
Thank you for the idea. This is possible today by configuring a default release for new and imported features. The status of this idea was out of date. You can learn more here: https://www.aha.io/support/roadmaps/strategic-roadmaps/settings/workspace-settings#configure
