Nop, no way, it's one of the shortcomings.
I'm actually amazed no ones bumped or given me a 'thumbs up' (lol) for the
shuffle program I have provided earlier in this thread, it does exactly just that! I only say this because the Alien Shozy was in the same position (at this time, unbeknownst to the community that there indeed was a hidden shuffle feature) and when I gave them this program it was met with a fair bit of enthusiasm!
Once again, please go to this page, look for my post and the links and details are within. What you want this program EXACTLY does;

FWIW, I now go one step further. With the assistance of my program provided in the above link and foobar2000 I am now creating single wav files that contain 50 or so tracks that are randomly shuffled and CROSSFADING into one another (so no gaps between tracks).
