You can set the profile to Convert to Searchable PDF by default in Detailed Settings so that all you have to do it press the Profile button on the scanner, and it is OCRd automatically. I didn't do this because it doesn't use the Abbyy FineReader engine by default, so I have Hazel grab the PDF and Abbyy FineReader OCRs the PDF via AppleScript.
Is this basically what you're doing: https://github.com/jbarlow83/OCRmyPDF/issues/180 ?
Any issues with the OCRmyPDF OCR engine? Do you change the file names later or just scan by date?
