Preparing title
If the GN4 title already exists, use that title. If it's a new print product, consider to create a new title.
Preparing sections
If the print product already uses the sections on the pages, then you can use the same sections for the partial names of the object libraries.
If the print product doesn't make use of the sections on the pages, then at least the pages that are going to be made up automatically need to have the sections assigned.
If using the same title to produce more products, prefix the section with the product name. E.g., if the product is named DEX, its News section has to be DEX News.
Remember to assign the default section folders to the product sections once you've created them.
