If I have a directory that contains multiple PDF files on Android, currently, it seems I have to click "Browse more files" for each file. This is very tedious and dumb. There MUST be a feature to import a directory from Android's shared storage into Acrobat Reader's app-specific storage.

On iOS, you can long-click a directory in the Files, click Share, and then choose "Save to PDF Expert", to import all the PDF files in the directory into that app. This is what I need.
