DocuSign - Sender

Hi everyone,

We are currently setting up DocuSign with M-Files using the workflow option. We would like the sender in DocuSign to vary depending on who initiates the process in M-Files. At the moment, the sender is always displayed as the account linked to the User ID. Did I overlook an option to change this? Is there a way to dynamically set the sender based on the M-Files user? (the red part in screenshoot)

Thanks in advance for your help!
