Thank you Mike for the answer, but that is not, what I meant.

The option you have installed works at all appearances of the song.
To my opinion it should be selectable for songs in setlists instead of songs only.
I use the same song sheet in a setlist to play only by myself and in another setlist to play together with some friends.
If I play by myself I use mobilesheet-audio as backing group. Then it would be comfortable to have a configurable time option before automatic audio start. I normally need some seconds to look for the song key and check the melody.
