Sleep timer schedule

Feature description:

Have a setting to specify a time range where the sleep timer will come on automatically.

Problem solved:

I often go to bed listening to audiobooks and I sometimes forget to set a sleep timer. It’d be nice to have a setting where I specify that any media I play between, for example, 22:00 and 7:00 will automatically turn the sleep timer on.

Brought benefits:

It prevents me from waking up the next morning with my audiobook still playing with no idea where I was when I fell asleep.

Other application solutions:

 
Smart AudioBook Player has this feature.
 

Additional description and context:

 
I really like Smart AudioBook Player but it lacks a watch app so I can’t use it with my watch

You can use the API and tasker or automate for that Symfonium API (Allow control from other apps like tasker) this will give you more power for automations.
