Sooo the best practice for now to make the player play alternate chords is to duplicate the chart and edit it and swap alt and regular. and just have a whole alt version and export the audio and splice it with an audio editor. Painful. Any ETA on this feature, the most brain dead thing to do would be play regular chords on odd reps and alt chords on even reps. Also a button that swaps alt and regular would at least make the editing very easy. If there's no alt it does nothing.
