In a previous version of Real Player - I could add a series of files to what now is now the queue and then select "randomize list" which changed the list into a random order.

Is this no longer available? I know I can use shuffle play but the difference, to me anyway, is when a track has played and the next starts, I cannot see which track has just played which I find useful because I sometimes want to hear the previous track again or decide I no longer want in the playlist.
