Modify all bookmarks at once
When using the "Combine Files" tool, we should be able to modify all bookmarks at once, without changing the destination of the bookmarks. For example when navigating the pages using the bookmarks, the files will open in a "Fit Width" view, unless individually modified to use "Fit Page."
I would like all documents to be viewed at "Fit Page" when using the bookmarks after combining the files, but I can only modify them individually, which is very tedious.
Please set Preferneces→Accessibility→Override Page display settings as per your needs. This will show the document as per your setting.
Further if you want to set the display for a document. Open File → Properties→ Initial View Tab → Layout and Magnification Setting.
Please confirm if this resolves your problem.
