It is possible to create buttons yourself via a web interface (name and destination are freely selectable) and arrange them on the touch screen as desired. However, I did not find an option for Google Drive. The Canon can transmit the scans via SMB or FTP, and additionally via e-mail or to an attached USB stick. I have solved it in such a way that the scans are transferred via SMB to a small PC, which then synchronises them to the cloud. It would certainly also be possible to transfer the attachment of an email to Google Drive via Zapier.
