Clear all device alert counters at once

Add the ability from the dashboard to press one button to reset all alerts on all devices on the system to zero or null. As it works with multiple devices today the only way to get to no alerts or to “start fresh” on the dashboard is to drill in to view each device. When I know I want to be alerted to new notices only it is best to start at a zero count. Forcing to drill into all 10 devices to get there is inconvenient.
