Thank you for the suggestion (just seeing it now because notifications don't seem to be working).
Your idea would work well if I interacted with Poweramp for playback. Unfortunately, I do not. I listen in the car. When the car is off, playback is paused, when the car is on, playback starts up again. (also via steering wheel controls for play/pause). Having a setting that when PLAY restarts, it starts up again 3-5 seconds prior to the previous pause point would be ideal.
