Increase freq sound in tracks

Today when I`m guiding with a track I can hear in my headset when Locus switch to next point (POI/Waypoint) in the track - fine !!

When I guide to a singel Waypoint/POI I can activate a very nice feature, Increase freq when go closer ! - brilliant !

My Idea/Wish is: Add the option Increase Freq also when you are guiding with a track and not only to a single Waypoint

The point is that you don`t need to switch on the display (save battery) or keep the phone in the pocket when it`s raining ;-)

Cheers
