To add pages from another document while bookmarking simply use the "Bookmark Inserted Pages" option.
- Bookmark Inserted Pages: Manage page insertions and their related bookmarks through a single operation.
- "Append PDF Pages as a single bookmarks"
- "Append PDF pages without bookmark"
IMPORTANT: If you select the option “Append PDF Pages without a bookmark” or “Append to the highlighted bookmark” and the highlighted bookmark has multiple pages (i.e. you only bookmarked the first page of a multi‐page document), the page will be inserted as the 2nd page in the document set. We are working to resolve this with our new Bookmarking code.
