Stories not Chapters

I am writing a book about 60 children with stress and psychological issues. I would like each chapter to stay on one character/protagonist. I have 6heir personal 0 individual characters with their personal profile and story outline.

I have clearly outlined that each character is independent. When I overview generation the program/Sudowrite limits the chapters to 25. I need a minimum of 60 character stories plus any additional chapters.

Question:

Is this culling and chapter limit due to me overlooking something, or is it a software limit? Can this problem be resolved by my approach or do you need to update your software?

Can I also change the “Chapter # Title” to “Story # Tile”
