How can I make a copy of any dashboard?
To make a copy of a dashboard, first open the Dashboard Details for the desired board. Click on Actions located at the upper right corner of the Dashboard Details popover window. When you choose an option Copy dashboard, a copy of the dashboard with all cards will appear in the main folder of your Google Drive and will be opened next to original board with the prefix Copy of. If you choose an option Copy dashboard layout, no cards will be copied, but only dashboard layout (list names and dashboard settings).
