paypal - Receive payments to a non-primary email address while doing reference transactions -

The merchant account I use is multiple email addresses and we want to receive payment at a specific email address. Anyone have any ideas on how this can be achieved? I'm not sure whether I can specify an email address when making a reference transaction or SetExpressCheckout or billing contract, or all of them to receive payments.

E - mail notifications for API call transactions will always be sent to the primary email address on the account - Pardon.
