splitting a document to rename individual files as bookmark name.

I work with drawing files, a single pdf can have 0-500 drawing sheets with in the single pdf. I use a take-off program OnScreen take-off that will convert the pfd into seperate tiff files, when this happens all of the files have the same name so i have to rename the files individally so that I know where to find a specific sheet.  The PDF's sometimes have bookmarks that are actually the sheet names, is there a way to split the document and rename the individual files as the bookmark name? I spend / waste 1/2 my day renaming files. please help.
