I have a company-managed project with a set of epics, and have created issues linked to those epics, then moved the child issues into different projects. I'd like to create a filter that shows all the child issues linked to all the parent epics. I was able to create this by listing all the parent epics individually, but if I add more epics I will have to modify the query each time. Is there a way to do this with a wildcard or "show issues in all projects when parent epics are in project x"?
