Open the dashboard in Edit mode.
At the bottom of the interface, hover over the (plus) icon next to the right-most sheet title.
Notice that a new widget, the (up) icon, appears to the right of the (plus) icon. Click it.
In the menu, select Import Sheet.
In the Pick a dashboard window modal, make the selection in the following manner:
Arcadia Enterprise creates a clone of the external sheet, and imports it into the dashboard, placing it on the extreme right.
Rename the sheet and click Save to save the all changes to the dashboard.
