Sure is, Wardonis. Go to your campaign's Details Page (click on "View Details" from your campaigns list). On the left side, underneath the campaign icon image, there's an option called "Copy/Extend Campaign." You can toggle what features you want carried over to the new copy. Once you have a couple duplicates of your master campaign, start cutting away pages from the clones so you have one bunch of related pages in one campaign, another related bunch of pages in another campaign and so on.
The only thing that you and your players will need to maintain/update at the beginning of a campaign switch is your NPC/PC's stats.
TY but I hope this will only need to be short term and that in time I we can have much larger campaigns
