I'm using the On Demand version of Jira. I need a filter that will show me:
All issues within a particular epic AND all sub tasks of those issues.
So effectively:
- Epic 
- Story 1
- Sub Task 1
 - Sub Task 2
 
 - Defect 1
 - Story 2 
- Sub Task 3
 - Sub Task 4
 - Defect 2
 
 
 - Story 1
 
Plugins are not an option here as I'm using the OnDemand version. Any suggestions on how I can achieve the above without having to link all sub tasks to the epic?
