Allow to select all alerts of a smart group (not only visible)
When viewing an alert smart group there's a possibility to select and edit all alerts at once. The issue is, that the "select all" option only selects the visible alerts of the current page. It doesn't select all alerts of all pages.
If there are lots of alerts in a smart group it's very painful to iterate through all pages and process the activities for every page.
It would be very useful to change the behavior of the "select all" option to really select all alerts (including alerts of other pages) or to add further select option to enable the desired activity.
