Notifying people of updated dashboard

Options

Is there a way to generate an automatic notification that a dashboard has been updated?

I know this may say a little archaic but I have a dashboard that updates once per week and I wanted to send to a target group (either by a scheduled notification or automatically when updated).

At this time, I have been "resharing the dashboard to the group", not a poor option, but looking for something more automated or system driven.

TIA
