I don’t use iTunes for audiobooks (I had an audible subscription that went unused and I finally unsubscribed, I’ve realised that I prefer reading physical books), but there’s this free OSX app called AudioBookBinder[1] that can bind a set of mp3 files into an m4a file and add it to iTunes as an audiobook. That might help in this case. [1]: https://apps.apple.com/us/app/audiobook-binder/id413969927 https://apps.apple.com/us/app/audiobook-binder/id413969927
