Find motion events by specified location of movement

Would love to be able to select an area on the playback and have clips produced from movement in the selected area. and no im not talking about live. only on playback.

USE: i have a broken glass on the floor…i want to see what kid or nanny broke it. I select a square area around the glass and then the playback goes 10x (a feature you have in the pipeline) and pauses when there is motion in the selected area. then i have a play and skip button. i just tap once to see next clip until i find the moment the glass breaks. Viola!

i spend waaaay to much time trying to find events so i can punish my kids haha.
