If I have a score with a 1st and 2nd ending and want to hear the transition into the second ending from a few measures back, the fastest way to do this is to click in the first ending and have it play all the way from the beginning of the piece to get to the 2nd ending. Even though I up the playback speed it takes a long time. It would be wonderful if I could click a few measures before the endings (or anywhere I want in the piece) and have some way to tell Notion that this is the 2nd time through, that it has already played through the first ending..
