Midi Playback Behaviour In Arranger Mode

Many times midi notes will continue from one arranger event onto the next arranger event, so why can’t those notes play out their entire duration rather than being cut of due to the arranger event ending. I understand that this is how the piece will playback after the arranger chain has been flattened but this makes it bothersome to work in arranger mode. If there could be a preview function that one could activate prior to flattening the arranger chain any edits could be made then rather than working with a system where midi notes are not being played because they started in the previous arranger event.
