I can certainly expand the CSV import feature to provide an option to split up the PDF into either image files or smaller PDFs. Before I support splitting up PDFs like this, I need to find a better solution than the rendering library I'm using as it produces files that are far too large, mostly due to not compressing the images on each page. I've found some open source libraries that may be better suited for the job, so I'm going to see if they produce smaller, faster PDFs. If they do, I will also use that solution for the exporting of PDFs with annotations.
