.NSF File Playback - Ability to switch tracks, prevent looping

I’m currently using Launchbox 11.7 beta 13. I like how Launchbox can playback multitrack NES Sound Format files other than bloated MP3 files. Though it would be nice if there was a way to customize the playback of .NSFs so some tracks within the files don’t loop endlessly, or so they could be played in a random order rather than sequentially.
