Good idea! In general I think that selecting targets should be made more "intuitive". Of course the "ALL" function is nice.

However, I have an alert that fires when a host gets above 80ms. Unfortunately, I have 6 hosts that always are above 80ms so those shouldn't be included in this alert. This means that I manually should select 240 hosts in the alert setup. <img src="/forums/images/graemlins/frown.gif" alt="" />

Perhaps there could be a "select all" and then afterwards one could remove those single hosts that shouldn't be included.

I attach a screenshot from an application that has this form of selection.
