It would be nice to have the ability to toggle only the PDF file format to be sent through the automated email sent once documents are generated. I have had a client who had this requirement which we were unable to fulfill and had to find a workaround for.
Adding my vote to this request with a twist… In our case, we would prefer DOCX only. So, I think the ability to select PDF only, DOCX only, or both would be a nice option.
I would like the option to receive DOCX and PDF, while allowing the client to only receive the PDF version.
