An Aha! feature can only be associated with a single release, however it is common for development teams to associate multiple fix versions with a issue in JIRA.
Currently, the Aha! feature will overwrite the fix versions in JIRA if the fix versions to not align with Aha! as the master copy. This causes problems when the intended workflow in JIRA is to have the feature associated to the fixversion -> Aha! release + another fix version used for internal tracking purposes.
