This would be something like a toggle, with the default being off.
But when toggled on, the markers would make a quick beep sound whenever they are played over. The main idea would be that it would make it easier to align the marker with a scratch/click. Once you get the beep and click to overlap, you know you are in the right area and can start manually trying to fix a click.
Interesting idea, thank you. We'll put it on the list.
