It would be great if a PDF (or however you have the product set up to export) was automatically generated upon order submission. I wouldn't package the export with the email, but provide a direct link within the email. In the New Customer Order email notification, instead of the "View Customized Product" link going to the FPD product page, you could have a link directly to the exported file.
It would also be nice if you could select the path for where the PDFs are saved. Dropbox, One Drive, Local server...
It seems this request is planned, so is there any info about it? I mean when can this be done?
