Allow to select all alerts at once
In the "All Alerts" view (see path below) it would be very helpful to be able to select/deselect all (visible) alerts at once and to change the state once. This option is already available in another view (see path below). If there are many alerts it's very annoying to select them one by one.
The attached screenshots show both views, where option is available and where it's not available.
Path to view where "Select all" option is missing:
Azure Portal > Monitor > Alerts > (choose severity) > All Alerts
Path to view where "Select all" option is available:
Azure Portal > Monitor > Alerts > (choose severity) > Alerts By Smart Group (Preview) > (choose group) > Details view
