I have reflected the activities in my Kanban Board into a JIRA Roadmap and inserted the associated Planned dates - creating the gantt chart view. This is excellent at giving me the plan.
I have custom fields to track actual dates - so we can look at any delivery / testing slippage in reviews etc.
Is there a way of reflecting these Actual dates in the Gantt Chart too - effectively creating a 2nd line for each feature - so we can see graphically any slip?
