The only workaround I have found for this is to:

1. Print all invoices to paper.

2. Change my (ScanSnap) scanner settings to create separate files for each sheet scanned. (It will automatically assign separate file names as it goes. You can play with the File Name Format a bit. For example, all file names can include the words Invoice or 2023, or whatever label you choose, at the very least.)

3. Pull out the invoices that are on multiple pages, to do separately later. (Otherwise each sheet in the one invoice will get separated into 2 files.)

4. Feed all the one-page invoices through the scanner in large batches.

5. Once scanning and file saving is complete, edit each individual file name.

I may skip #5. because my scanner allows for OCR, so I can find the invoice I need by utilizing that feature without the need to rely on the file name. For me, putting them all in a folder identified by the fiscal year is enough.

Hope this helps!
