Chime when auto finding parking space?

On my MY17 L&K, the auto-parking is really neat.   The main problem I have with it is when its scanning, the display will indicate the space is suitable and shows the reversing image.  If you're concentrating on the vehicles around its easy to miss the transition from scanning to wanting to reverse and end up moving a few metres further forward that then changes the image back to scanning - ie, you've missed the space.

It'd be really useful if the dash would 'bong'/'chime' when a space is detected.   I haven't seen anything for this functionality, is it possible via VCDS or has anyone enabled such functionality?

Thanks
