Using Adobe Sign in Flow

I don't think so, out of the box at least in their current implementation.  If one were adventurous enough I think you could import the adobe sign API w/ swagger 2.0 and have your own "custom" app in flow.

Hi Adennis,

You may use tags to create the form field in Adobe Sign form.

Refer to this help document Use Text Tags to create form fields

Check if this what you are looking for.

If you are trying to add some specific form field type in the form, please provide us with more information.

Let us know if you have any questions.

Regards,
