Can I recover a custom PDF template?

I accidentally applied a stock template to a JotForm in your PDF editor, seemingly overwriting a custom template I created. I spent a ton of time on the custom template, and I'm hoping it can be recovered.

Please note that the Undo/Redo options can only be done when the changes made to the document are for the same session (commands CTRL-Z for Undo). The changes history for the PDF document is not available if the PDF editor is closed or reloaded. 

Now, if you saved the previous TEMPLATE, you can revert to it by using the template again. But if it was not saved and there were changes made to the PDF, unfortunately, that can no longer be reverted.

Got it, thanks for the help!
