Integrate chapters and reverse chapters updating

I began using Sudowrite in 2024 and published one book using it. I need a function to integrate 20+ chapters into one large novel. Once I've edited the integrated doc, I hope to revert the updates to the individual chapters. I write in multiple languages and need to translate one chapter at a time.

I know you have already developed such a capability. Please arrange a training session for this integration and reverse chapter updating.
