On a lot of songs I unfold and make an ending before the auto ending. On the first bar I use a part marker (for the drum fill)second bar I use a hold chord and let it hold for 3 or 4 bars and add a shot chord or not at the desired end. Also cut and paste parts from the auto-gen ending if I like them. A long way around ,but doable . I think this should be kept at the top of the wish list till PG can fix the problem .
