Can Signers Choose Where to Place Their Signature?

Hi everyone,

I'm using the Adobe Acrobat Sign API to create agreements programmatically.
From what I understand in the documentation, it's required to predefine form fields (like signature fields) and place them on the PDF before sending the agreement.

However, I would like to know:
Is there any way to allow signers to choose themselves where they want to place their signature on the document?

Ideally, they would receive the document and be able to click anywhere to place their signature without predefined signature fields.

If this is not directly supported via the API, are there any recommended alternatives or workarounds to achieve a similar user experience?

Thanks in advance!
