Sender as a Signer

Hi Duo, 

I was trying to send the transaction to sender for signing as well. In some of the instances in our use cae, there might be a case where the sender also needs to sign the transaction. If I am not wrong, I had gone through similar blog or forum where the discussion revolved around using sender as a signer. Regardless, how do we achieve this case(using sender as a signer) ? I tried but the sender never received an email to sign the transaction. 

Can you please help ? 

Hello, We're currently running into an issue when the sender of a in person package also needs to sign a document within that package. Using the instructions specified in the Signing URL Guide we can still open the signing ceremony, but the sender will not be listed in the drop down that contains the list of signers.
