Maintain page label numbering for each pdf when combining pdfs.
This is for combining court transcripts that are prepared using block numbering pursuant to California Code 8.144. Each day of court proceedings is assigned a 300-page block, so if one court date has 130 pages of transcript, page 130 would be labeled 130-300. The next page number would be page 301. Pdfs for each date are then combined for a given case into one Pdf. The page labels with Adobe are not maintained after combining the pdfs, so what was labeled page 130-300 becomes page 131.
