Modifying automatic page navigation / numbering

I have been using Commentpress to allow translators to work on translating antique Japanese manuscripts between 100 and 400 years of age. It has been a very successful experiment thus far. https://hidensho.com/

I wish to be able to post more than one document for translation. While I’ve had no problem using the Parent feature to create a collapsible menu in the left-hand column (using Commentpress-Modern theme), I have run into a small problem with the automatic page navigation / numbering feature.

Your system’s menu presently views each of these collapsible sections (pages with a parent) as a Chapter in a book, continuing the automatic page numbering sequence through Chapter to Chapter.

The way I am using Commentpress, each “chapter” is actually a separate project, and needs to have child pages counted starting at the number 1. Is there some way to reset the automatic page numbering to 1 for each chapter?

If this is difficult or impossible, how can I filter out the automatic page number, while still leaving the automatic forward / back arrows? I can easily establish the page number in the title. but keeping the navigation arrows would be a must.

Thanks in advance for your help!
