one recipient email with multiple roles?

We have a situation where we want to send a 'take-it-or-leave-it' agreement to a recipient.

This recipient will be a signer (although in a 'received-and-acknowledged' capacity),

but the agreement also needs to be signed by an authorized signer at the recipient's

organization, whose identity is unknown at the time of sending.

Ideally, we'd like to list the first recipient's email for both roles, and let them (or require them to)

delegate the second signature to the authorized signer when they get the email from Adobe Sign.

I see Enterprise now offers a "Delegator" role, so I guess with the appropriate upgrade, the

question now would be does Enterprise allow you to specify the same recipient email address twice

but with different roles.

Thanks,

John
