"In/Out Bits per Second" Widget not available in Network Dashboard, only Interface Details.

I am trying to add the "In/Out Bits per Second" widget to my companies Network Overview Dashboard but it is not available. Is there a way to add a "Node Interface Widget," to a Summary Dashboard? When I select "Add Widget" within the Dashboard overview of my companies network, the widget "In/Out Bits per Second," that is available when under the "Interface Details" dashboard, isn't available to add in the "Dashboard widgets." Is this something that can be done?
