I there Larry,
Although there are several options, best is to say No; the options available are too akward. See screenshot below, which starts with selecting Library Items and then rightclick.
Notice that once you have the Playlist Area filled with tracks, you can select tracks in there by means of subsequently clicking them in there - in a random sequence. If you now click Play, the ones your selected will remain in the Playlist Area and they are now in there in the sequence you selected them. Click Play once again, and all plays in that (though visible) sequence.
Also, keep in the back of your mind that XXHighEnd is meant to play Unattendedly (see button "Unattend" under Play - GUI will disappear), which makes this kind of functions less easy to create. So with the Playlist remaining visible and the active "control" this would all be different, but as this is not the advised playback means to begin with (SQ reasons) ...
Also notice the Short Cuts for when playing without GUI :
AutoHotKeys (Remote Commands) Listing.
Kind regards, and welcome here !
