How do I add a box for drawing signatures?

[RXTF]

I have the latest version of Acrobat Pro...

How do I add a box that allows a user to draw a signature? Currently, I only see a way to add a digital ID signature block.

Thank you. I look forward to your responses.

There's no such element in PDF files. The user can use the Pencil tool or the Fill & Sign tool to do it, but you can't restrict them to only use a specific area on the page for that.

Really? Because I have filled out PDF forms and clicked a signature pad, then was instructed to draw my signature.
