Receive a copy of the completed form in the same format that person filling it out receives

We have vendors fill out survey information for us, but the format that the vendor receives their "send me a copy of responses" is a much better format than we receive as a workflow notification. We have dozens of optional fields and they receive only the fields they filled out. We would like to also have that format come in to us. Does anyone know how to do that? Currently I have to do a generate PDF fillable form to at least get it to a format to use and it takes an enormous amount of time to customize each one.
