Addbookmark.vbs

I am using Scripts\\RunProgramBeforeSaving\\AddBookmarks.vbs to add bookmarks to my PDF File.  I added the program using the action tab, actions before saving.  I would like to also name the bookmarks so they are not page 1, page 2...  I noticed that the program parameter says .  Where does this come from?  It seems to be a temp file generated with a counter but I do not know where the name/counter is stored?

Also, could I modify the vbs program to accept another argument(s)?
