We are trying to use JIRA for Scrum of Scrums so from the Master Product Backlog, we need to assign User Stories or Tasks to other Product Backlogs (since more than one Apps are involved here for design & development and each App will have a Project and Product Backlog)
Presently there is no way I can assign a user story or task from Master Product Backlog to other Product Backlogs - it allows only assignement to Persons or group
End goal is to have a single view from Master Product Backlog / Sprint Backlog for the entire project
