Is your feature request related to a problem? Please describe.
When I scanned a whole bunch of documents, everyone a single file/document (e.g. coming back after a long holiday and scan my snailmail), I am ending up wither either one single PDF file with all documents in it (Export function) or JPG instead of PDF files (share function).
Describe the solution you'd like
I want to select documents in OSS Document scanner and export all selected file into one location as SINGLE PDF files instead of one single accumulated PDF file.
Describe alternatives you've considered
For now I have to export every PDF manually to have a single PDF file created at my export location.
