Adobe Sign Sent Out Email Changing

Hey everyone,

I've got about 40 users currently using Adobe to send out e-signature requests to clients, is it possible to have the email address that gets sent to clients come from a default email instead of their work email address. 

For example, John is logged into Adobe with his work account "john@example.com" and sends out an e-sig request to a client, instead of the client receiving an email from john@example.com,  could it come from admin@example.com without having to sign into a seperate account and doing this?

Thanks!
