Audiobook for fiance

Hi, I'm looking into physical audiobook options, want to record a book for her and I know she loves to have the item physically instead of on her phone.

So far I have found the best option to be in the form of a CD or multiple CDs, but I've also seen something called a playaway which looks way better storage wise, but I couldnt find a way to record my own chapters into one.

Does anyone know of something similar to a playaway where I'd be able to import my own chapters that she can listen / skip through?

Thank you so much in advance!
