Schedule BIP Report notification server without Credentials in Payload

Summary:
scheduleReport operation in the ScheduleReportWSSService wsdl requires notificationTo and notificationPassword to be set in order to use the notificationServer. Is there a way to avoid sending the credentials in the payload? Instead, I'd like to use the credentials passed via basic authentication.

Trying to schedule a BIP report with the notification server option, by using ScheduleReportWSSService wsdl, Operation - scheduleReport.

This service schedules the BIP report successfully, but requires notificationTo/notificationPassword
in the payload itself in order to make the notification server call work.

 Is there a way to avoid sending credentials in the payload and still invoke the notification server?
