I have just been doing some work on reports in NCM in particular the "Last Inventory of each Device" report the issue I have is that you cannot sort by the date field more digging and it is the same for last rebooted report. I would suggest for both these reports there is a good chance that most use cases involve taking a view of when something happened so it would be good to be able to sort the reports by this field in the UI.
