When creating a lead sheet in PM Pro I always (without exception) need to enter custom chords. They may be leading chords that are outside the key of the default key selected or specific slash chords. After completing the layout to my satisfaction I save the file and, upon opening it again to make edits (don’t we always make edits!!) all of the “custom” chords I have created are gone from the chord list. They are, thankfully, still in the lead sheet. Why aren’t these chords saved in the list as part of the song file? Am I missing something? Any assistance would be greatly appreciated.
