Sleep timer: x chapters

[jakob42]

Is your feature request related to a problem? Please describe.

I'm trying to use ABS for my kids audiobooks during bedtime routine. At least the younger one isn't old enough to decide on her own and I usually have a sleep timer for one story (often a chapter.) That seems possible with the android app. Some stories though have chapters themselves and another story right afterwards. at the moment a cannot play them in audible reliably

Describe the solution you'd like

I would like to be able to set a sleep timer for x chapters, e.g. three. It could be located in a pop-up, reachable next to the sleep timer til end of chapter. Manually seeing the sleep timer for a time would be complicated since I would need to check the runtime for each chapter and set a manual timer. (Which isn't possible at the moment anyways.)

Thanks!
