Notes for songs

Wondering if a small notes section can be created for each slide in a song that can only be viewed by the presenter (I guess it may be beneficial for the stage display as well?). At issue is the possibility that the one advancing the song slides isn't as familiar with the song (especially if the song is playing from WE) and advances the slide too early. My suggestion is that a notes section be available to input the time of the song to advance the slide.

Notes for individual slides, e.g. Intro, Instrumental/Interlude needed to see how many measures long.
