If you want to keep pages in bookmarks separate instead of combining them into a single bookmark when the same bookmark value is found in several interspersed images in the batch do the following:
1. Open the Job Configuration file in Notepad.
2. Search for this value: <BOOKMARK_PDF1>
3. Enter this directly above the line that has <BOOKMARK_PDF1> if its not already there: <BOOKMARK_UNIQUE_LEVELS>-1</BOOKMARK_UNIQUE_LEVELS>
4. -1 is the default value and that means that no pages should be combined into one bookmark unless they fall in order. 0 means that the first bookmark level should be combined into one bookmark value and the rest should not. 1 means that the first and second bookmark levels should be combined and the rest should not be. ETC.
