Is there a way I can get roll-up dates from Epic items into an export file or Confluence database?
Roll up dates on your timeline | Jira Cloud | Atlassian Support
We use epic items to track the progress of deployments in various factories. I would like to get insights into the total lead time (start date --> end/due date) for every deployment and have that into a format that can be exported (to excel for example) such that I can start tracking metrics like "average lead time per deployment" etc.

I have made an overview into a Confluence database of all my epics, but in the database I can only get the start date + due date values of the epic if they are overridden into the epic itself, it does not show the roll up values.
