I'd like to get JIRA epics to aggregate subordinate story/task estimates in hours/days/weeks (not in story points). So that when viewing an epic I can see what's its total estiamte, remaining and actual in hours/days/weeks, and also so I can see the epic burndown in hours/days/weeks.
I can get stories and tasks to aggregate subtask times, but I can get this to work at epic level, is there a way to achieve this ?
Thanks!
