Peak Position

Please can we have a feature that tells us where the peak of the OVERALL MIX is (i.e. in terms of timeline units), and its value. I understand that this may not be possible as a real-time, self-adjusting thing. But can there be some sort of process that calculates it by analysing (or perhaps internally rendering then analysing) a chosen output (normally the master / stereo outs). Essentially this is to save all the time it takes to play the entire ‘song’ while watching the faders/meters and noting down on paper where the max dbs happened. Thanks!
