Hello!
I wolud like create a board based on some JQL selectig epics. If I write this JQL I can see only epics on board without stories and sub-tasks.
For example, I have filter like this: "project = TEST AND type = Epic and component = Backend and assignee = someUser". But if I use this filter directly I missed stories. I mean, is it chance to emulate some JQL sub-query for this dedicated case
