Regarding your question about BeCyPDFMetaEdit:
BeCyPDFMetaEdit does have some capabilities for editing metadata of PDF files, including the index. However, it does not specifically provide an automated feature to adjust the page index for all pages at once in the way you described. You would typically need to edit page metadata manually on a page-by-page basis, or use a different tool that offers batch processing for this specific task. You might want to look into PDF tools that support scripting or batch editing for more complex tasks like adjusting index pages automatically.
