This is a must for real estate, it is common that the sender will not be a signer and that there will need to be multiple sellers, buyers and others... we should be able to either with a workflow or api be able to assign names and email address for signers who are not the primary contact.

Yes you can do this now but it is a manual process if you could have contacts associated with each other be able to sign

You can do this now - you add contact on the left side by clicking the people icon - click the blue button 'add client' then you can click the signature box and itll pop up on the right hand side to change who signs.

UX for this is trash and why people dont know how to do this. Too complicated. - so improvement for this request would be to make UX and functionality easier for multiple signers.
