Feature Request: Temporary or Quick Alarm on the camera

There are a few times when watching a live camera where I have wished I could setup a temporary alarm, so I was wondering if an alarm button could be added to the the image controls on each camera (Rotate, Info, Zoom Window, Motion Search, etc.) When pressed it would let you draw a box, a specialized motion zone, around a specific area and then pick one of the sounds to play as an alarm. If something entered that area it would play the alarm.

As long as that button was active the box would always be visible on screen and of course play an alarm when triggered, and if turned off the box and alarm would be hidden or ignored.

I'm imagining something really quick to add and remove right on the camera view, like the Zoom Window is, and not an elaborate secondary dialog the pops up with lots of extra settings like the camera rules or camera settings boxes.
