I have an expense report program where I import receipts (PDF) to container fields for each day of the week. Looking for a filemaker solution where I can collect the container fields (receipts) and create a single PDF file that contains the expense report plus attached receipts. The shortcomings of filemaker where I cannot append when using Export Field Contents, or create an email with multiple attachments has me doing things manually instead of a one button operation. Comments/Solutions appreciated.

The "save as PDF" can append to existing PDFs, so you can do multiple passes through the attachments and keep appending to the PDF you created.
