Can I have a default template name for pdf

I currently have my form set to attach the PDF of the form to the email notification. I would like this pdf to be named a certain name instead of the generic numbering that is on it. Can this be done?

Unfortunately, it is not possible to rename the PDF file attached in the submission notification. The name will only be based on the submission ID of the form. 

However, you can still rename the PDF submissions in the Dropbox or Google Drive integration.

Here's a guide that you can follow: How to setup folders using UniqueID in Dropbox. The guide uses the Unique ID widget, but this guide is also applicable to other form fields in renaming the submission that will be uploaded to your Dropbox.
