When setting up integration with JIRA it often happens that old relases and features are transferred to Aha if their statuses were not well maintained in JIRA. To get rid of those is a big manual task(manual delete of features and then the releases). The manual overhead could be greatly reduced If there was a bulk delete function where one could select all the releases that should be deleted from Aha together with their assigned features (this should include the Parking Lot 'Release').
Thank you for your idea. It is currently possible to bulk delete the features within a release. Using the Features > List, you can filter based on release name, select all features, then bulk edit and delete. You would need to manually delete the release itself, but bulk edit should speed up the process dramatically.
