esign fillable forms in a journey

Summary:

Looking to see how we can add a fillable form in a journey with an esignature. I tried to configure with Configure Native Electronic Signature in Journeys however, I am not seeing how using the RTF file we can make the form fillable. From what I am experiencing the RTF file can have printed info on the form like a policy and at the bottom we can include the esignature items.

So in sort is their a way we can have fillable forms with an esginature in a journey similar to the way you fill out forms in Docusign and then sign it.
