I see what you mean, can you share the designer/preview link so I could take a closer look?
If not, how many different types of book would you have?
One possibility is to create new collections if it’s only a few, so for example recently I created:
This meant I could potentially style/order each template page.
Or you could just create new pages and add a dynamic list to them, i’ve done that with a ‘View all’ page and a ‘Sale’ page, with the filter/visibility/sort by customised for each page. If you have those multiple order number fields, you can then select which one.
Have a search around the forums for how people have used categories, sub categories, reference and multi-reference fields too which might help. Or if you can share your link we could take a closer more specific look at your project.
