Adding dynamic qr codes to cells to be used for mailing

[Mailbot]

Hello,
I am creating a mailing database and each row has a unique QR Code. I need to use this spreadsheet for creating the mailing that will print the QR code next to the address on the post card. Does anyone have suggestions on how to add a QR code to each row? When I use QR4Office, the image only "floats" above the spreadsheet. I have 10's of thousands of addresses which means 10's of thousands of QR codes. I also am trying to find the easiest way to create a spreadsheet after the cards come back. Scan QR code into spreadsheet. thanks

Still hoping someone will know how to work with images in a cell? If we can use QR codes in our database, we would be very excited!
