We create an epic long before we actually plan to start the work. Planning takes place over a month or two before we begin executing.
I would absolutely love to use more of the charts and visualizations of my epics (and sprints for that matter), but they can be ridiculously unnecessary to read (see screenshot).

Is there any way to fix this? What should have done instead? Only create an epic when we're about to start?
Why does this chart not have date controls like the Control Chart?
