It would be incredibly helpful to have the ability to swap individual pages within a PDF document in the document viewer. For example, I may upload a 150-page financial statement, perform various checks (such as using "find all sums" to ensure accuracy) and add comments of my reconciliation the financial statement to accounting records.

Occasionally, I might find 1 or 2 pages that require corrections. Instead of re-uploading the entire PDF and repeating all the previous work, it would be much more efficient to simply replace those pages with the corrected ones. This feature would save significant time and effort, allowing us to preserve the completed tasks while updating only the necessary pages for a final, accurate document.
