Measure True Peak of entire 5.1 audio file

I am looking to measure the TP for a 5.1 audio file. I need to do this for Dolby Atmos loudness specifications. So doing an amplitude analysis and getting the TP for each channel doesn't help.

 

I can do this in Pro Tools (audiosuite/offline analysis) using iZotope's Insight but I was hoping to find a way to do it in Audition. Is it possible?

If you open the 5.1 file in Waveform view, and open the Ampliture Statistics, the true peak amplitude is the second entry. If you select the whole file and scan it, it will analyse each channel separately, display them in a row, but still give you a true  peak values for each. Pretty easy then to spot which channel the highest peak is in.

Thanks for the input. I think my original understanding was wrong in that the Atmos requirement was the measurement of a TP for the entire file, not individual channels. But I think it IS on a per-channel basis, so no channel can exceed -1dBFS
