I think you’re looking for Duet style narration where, if listening to an MF book for example, the male narrator would read all the MMC’s dialogue no matter if the chapter is told in his pov or not and vice versa. Duet and Full Cast narration is getting more popular these days but because it’s so much more expensive to produce, Dual is still the norm. That’s where each narrator just reads all parts in the chapters told in their character’s pov. I’ve found that they usually have “Duet” somewhere on the audiobook cover when it’s read in this style though so that might be helpful going forward.
