In the display, it is possible to show [Remaining Time] and [Total Time] for a single track.
It is also possible to show [PN Position] and [PN Tracks] which implies that the contents of the "playing now" list is available to the display.
My question: Is it possible to show remaining time and total time for the playing now list rather than for a single track?
(I looked for, but didn't see, documentation on available "PN" fields.)
