When using the book export, it would be wonderful to have the option to export the documents that make up the book as separate PDFs.

This option would be useful whether exporting the entire book to PDF or exporting selected documents to PDF. Metadata embedded in each document of the book would be included in the export to pdf.

For example, I currently create a journal using the book function to pull together and organize the separate INDD files for the cover, TOC, and articles. Once the journal is completed, I need to generate the following PDFs:

1. Entire journal as pdf, two versions: 150 ppi and 300 ppi (easily done with current PDF export)
2. All journal articles as separate PDFs at 150 ppi for website use
3. All journal articles as separate PDFs at 300 ppi

Steps 2 and 3 currently require opening each article and using two different pdf presets to generate the 150 and 300 ppi versions. When there are 20 articles, this becomes quite tedious. The option to export separate article PDFs in a single export action would be an amazing time savings.
