Take a look in the 'status bar' at bottom right of the Response Table.
You should see a 'clock' icon.
Move cursor over it and you should see it expand and say 'history'.
Clicking on 'history' will display a 'history bar', you can than click on any time in the past and display the 'historical snapshot'.
You can then view and copy (by highlighting and copying a la Excel) and pasting into the current view.
Hope that helps. Good luck
