As of now, the current feature has the ability to edit the Start Date and the End Date of a sprint.

Looking at the screenshot attached, you can see that we were able to change the sprint start date from Nov 1 to Oct 22, that's not a problem.

The issue is that the other sprint event dates (you can see them at the bottom of the screenshot listed as event type Scope change) cannot be modified anywhere. It will be useful if there is a feature introduced that allows users to be able to modify these dates.
