How to customize/turn off specific sounds? (climbpro, navigation etc.)

I recently got the Edge 840 and while some of the alert sounds are useful, many of them are pretty annoying to me. It would be awesome if we could customize them more.

Here are the sounds I’d like to be able to turn on/off individually:

- The first tone when it alerts you about an upcoming turn (I only need the second tone right before the turn)
- ClimbPro tone at the start of a climb
- ClimbPro melody when finishing a climb
- Melody at the end of a ride/when completing a route

It would also be great if there was a way to adjust the volume of these sounds.
Does anyone know if these options already exist or if there’s a workaround?
