Custom name for PDF attachments

I have an event setup form, with a pdf attachment to the notification.

Right now the attachment is using the event name and the event date (the first two form fields) as the attachment name. This is fine, but I would like the date first and then the event name, so that when I place the attachments in a folder and sort by file name, they will be in the order of the event date.

If you're referring to the submission PDF attachments, you can rename it via the PDF Editor.

Here's a quick guide for that:
