A document can be turned into a single scroll, or multiple pages can merged into a single long page, by selecting the desired pages in the Page List, bringing up the contextual menu and selecting Merge Selected Pages.
The resulting new page consists of a blank page, tall and wide enough to fit all of the merged pages, which are stacked on top of each other as static annotation objects, allowing for further tweaking if desired. The merged pages are removed as individual pages in the document. After exporting the document to PDF, the merged pages are burned into the new page.
