Can i create multiple pages?

You can make use of the following

{
	current: 1,
	pages: [
		{ components: [], style: [] },
		{ components: [], style: [] },
		...
	]
}

When you change the page, at first you store the current template:

const currentPage = pages[currentIndex];
currentPage.components = editor.getComponents();
currentPage.style = editor.getStyle();

and then you change the editor with the next one

const nextPage = pages[nextIndex];
editor.setComponents(nextPage.components);
editor.setStyle(nextPage.style);
