for that i believe you would have to make a script with the scrolls inside of the script. Then after you do that you will need to make a command inside the script as well such as /use which would be allowing you to make the items combinable so when you use the /use method the will turn into a book and not just stay as a scroll
Afaik support is in the core (and has been for a long time), and it should work live-like. But for the hell of it I can't recall how that exactly was :p
