Wanting a Text Field to be included in the form submission in pdf form

Is there a way that I can make a plan text field (not an entry/data field for the submitter) appear on the form submission that is sent via email in pdf form?

I want an OFFICE USE ONLY area on the form, and I created one via text but it won't show up on the email submission unless I include it in the email form, but even then it doesn't appear on the pdf of the submission which we greatly prefer.

For the PDF version, please enable the Show Headers and Text in the Submission Panel. Here's a screenshot:

To open the Submission Panel, please check this guide: How-to-View-Form-Submissions

For the Email content, you need to manually add the Text to the Email content and Save it. Here's a guide: How-to-Edit-the-Email-Template-for-Notifications-and-Autoresponders
