Configurable actions for Android Auto previous/ next buttons

Feature description:

I would like to have options in the settings to configure the behaviour of the previous / next buttons in Android auto.

Problem solved:

I primarily use Symfonium to listen to audio books, which I primarily do while driving.
Not having the ability to skip 10s forward / back is quite annoying.

Brought benefits:

Using Symfonium for audio books would become much more pleasant for Android Auto users.

Other application solutions:

 
The audible app for example has 15s forward / back skipping in these controls. It’s not configurable there, but this behaviour is what I am looking for.
I understand Android Auto is very limited, but configurable actions should be viable considering the configurability that’s already there (tabs etc.)
