Segment overview to identify where segments are being used in Dashboards or reports

Description - Have the ability to monitor segment usage such that we can know impact of either deletions or modifications of segments. 

Why is this feature important to you - Allows a fast and quick way to manage segment usage and speed up QA of any segment changes

How would you like the feature to work - Perhaps some extra column info in segment manager where once a link is clicked all impacted dashboards or scheduled reports are listed. Also notes if any segment is not used by either dashboard or scheduled report

Current Behaviour - No way exists to day to do this
