We do audit all data changes as they happen, and we also are versioning data nightly to provide information consumed in our charts sush as the burndown. So the bones are there, we just need to provide a way for users to view the historical data, and perhaps even revert back.
I do know that displaying the history for a story is on our radar and I believe this is scheduled for our Q3 release (October timeframe I believe). I'm not sure if we have scheduled any kind of 'undo' or 'revert to version' functionality at this time, but we will certainly note the interest in it and prioritize it accordingly.
Hopefully you can get your PM onboard, as we believe that TeamPulse is a great product and will be improving leaps and bounds with every release going forward.
All the best,
the Telerik team
