Nextpage

Hi and thanks for this great plugin.
I’m trying to figure out how to split a long page created with
pagebuilder, but I can’t seem to find a way to do it . Looks that
a widget with the nextpage function whould proove helpful in my case
at least. Is there anyway to insert a nextpage tag without affecting
the format of the created page or reverting the page to normal wordpress
editing tools (which is problematic for long pages)?

thanks in advance
