I have a team and want to implement a handful of themes (epics) by a certain date. To coordinate with other teams, we plan in "stages". The epics are either roughly estimated (based on historical values) or finely estimated because we have already worked out the associated stories. Estimation we do based on Story Points, which are noted in the Epic as a total. I would now like to craft the Epics in a timeline with several milestones so that they best fill the individual time periods. Is there a good editing option for this in Jira or a plugin or a completely different tool?
