Dear JD,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, it seems that you are trying to populate 10+ pages notebook to 7 class teams per year group, need the students to be able to open their own version of the pages.
If the understanding above is right, we're afraid that you will need to do this manually by distributing pages to the Class notebook or individual students or student groups. Please refer to below official article for more detailed information.
For your reference: Distribute pages and sections to Class Notebooks - Microsoft Support
We hope the above can help. If there are any updates or we don't understand you, feel free to let us know.
Your understanding and cooperation are highly appreciated. Thank you for your precious time. Have a nice day!
Sincerely,
Rhoda | Microsoft Community Moderator
