Is there a way to add my old submissions to Google Drive?

I added a google drive integration and finally got it working. But it does not regenerate the pdfs from previous submissions. Is there a way to force the integration to add the previous submissions?

There is no way to send directly your existing submissions to Google Drive. Our current integration only sends the submission when it is sent. However, you can edit your old submissions and it should send a copy to Google Drive. In order to edit your old submissions, you can follow this walkthrough:
