This is one of those
"I can't use Alert Central without a feature I need first"
Our first line of defense (i.e., who gets notified first), is almost always SMS. Therefore, we have all the SMS addressing, and scheduling, set up in Alert Central. ... but, then everyone who is in the on-call schedule, whether they're actually on-call at the time or not, ends up getting an SMS Saturday nights @ 23:50. This alone makes using Alert Central in our organize impossible, never mind the other deficiencies.
No offense, but it's pretty silly, in my opinion, that options for this, or at least an On/Off switch, are not included.
Thanx

P.S. I searched, and found nothing specific to this already posted as a feature request.
