When adding a book, it would be helpful to have a simple switch to mark if we are reading in more than one format at the same time. Many readers switch back and forth, for example listening to the audiobook during commutes and then reading the physical copy at home.

If the switch is turned on, we can just tap to select the formats we are using (Physical, E-Book, Audiobook) and choose how we want to track progress (pages or percentage).

This would make tracking more accurate for hybrid readers without adding extra steps.

The goal is to track multiple formats as a single read
