Expense reports
Say “for an expense report” in a search, and get a PDF you can send.
Ask for one by searching for what you need and including “for an expense report”. The results then offer to create a PDF. Menu ☰ → Utilities → Expenses does the same without a sentence: search for the receipts there, add the ones the report is for, then create the PDF.
Then send it. “Send it to an app” opens the phone share options, and “Email it” opens your mail app with the PDF attached for review.
Search the way you would anywhere else — a bucket name, a month, a shop — and add the results one by one. Only the receipts you added are read, and only when the PDF is created.
The pictures are read, shrunk and printed on the phone. Nothing is uploaded.
