Compile Select Chapters of a Serial Novel

I’m releasing my novel in serial form, and I can’t figure out how to compile Chapters 7-12 in such a way that the resulting epub file numbers the chapters as such. Instead, it automatically turns Chapter 7 into Chapter 1.

Is there any way to fix this? Does anyone have any fun workarounds? Should I maybe just switch careers?

You can do this by selecting the section you want to compile from the popup menu at the top of the righthand pane in compile–so rather than the full Draft, you’d have just the folder representing Chapter 7, for instance–then deselecting “Treat compile group as complete manuscript”. This will cause the counter placeholders for numbering chapters to count the previous sections even though those sections are not included in your current compile.
