I have a project with the key say XYZ. When I create epics or US in that project they all get named XYZ-1, XYZ-2, and so on, randomly. I cannot distinguish whether an item is an epic or a user story(except for the symbol/icon, of course) and are parent-child as well. I basically am looking for some indicator that shows the parent-child relationship between an epic and the US.
E.g. Say if I have an epic XYZ-23. I would like to have a naming convention like XYZ-23-1, XYZ-23-2, and so on or something on similar lines for the US of that epic.
