We need to be able to send to Adobe via a CONTACT, not an email.

With Adobe you can have users sign their documents directly inside the SF-Community Portal. For this to work, we need DocGen to be able to send to a CONTACT in stead of an email.
Currently one can only select a fixed CONTACT. We'd like this to be extended so that we can use a dynamic contact, from either a Relationship or via a button-parameter. Then enter that contact in the Recipient field with a Tag, just like dynamic name/email recipients.

W/o this feature, we are not able to implement Community Portal Signing with DocGen. We have to send an email to a user, user has to go from the portal to their email, open the email, sign, then go back to the portal. Not very user-friendly.

To work-around this DocGen shortcoming, we are going to use the Adobe-API to pick up a document and send it to a Contact.

If we can do that with Adobe-API, why cann't Nintex do this?
