I don't have ScriptRunner, so please don't show solutions using ScriptRunner.
I want to show all EPICS in my project and all child issues of those EPICs in the search results for a major bulk edit operation. In my previous job I had ScriptRunner and it was easy with ScriptRunner. I've tried a multitude of statements including trying to get parentEpic to work for a "filter" of the EPICS. Any help would be appreciated.
