It would be helpful if we can have "Attachment" as a Field readily and directly available to add/use while creating Advance Web From instead of first creating a Template, add envelope/document to it then add attachment field to it so that it can be available to use while creating Web Form off of that Template. It would be of a great help if this Attachment field is readily available to use(like other fields such as Text, Drop Down, Check Box etc) while creating Web Form from scratch without using any template. 

I am using Smartsheet to create web forms but if DocuSign can provide this Attachment Field, then it would help to lean towards DocuSign rather than Paying additional cost for Smartsheet to create forms with attachment field. I am sure many users would benefit form having this feature in DocuSign Web Form.
