In this scenario, there is one Program product workspace in Aha! and one Program project in JIRA which contains Master Features per Agile Release Train. All Stories (Aha Features) and sub-tasks (Aha Requirements) are with one or many Agile Teams (Aha Products).
Master Features should be sent to the Program Level project within JIRA, instead of team boards. However, the Features related to the Master Feature need to be sent to different JIRA projects (team boards) based on the team working them.
