I am looking to build a Project in Jira were we are able to see all the ongoing projects, epics, issues from different teams within the department. I just want to know if it is possible to give different teams epic a different Project key and still see the report in a common board. there are 15 teams with multiple projects within every teams, so multiple tasks , issue, epics within each team. Is it possible to create such a setup, if so how can we do so?
