How to receive the Nonprofit rate in a MailStream Plus presort

Affected Products:  MailStream Plus
Product Feature: USPS / Postal
Operating System: All Platforms

MailStream Plus by default will give the Regular rate for all mailings.  To change to the Nonprofit rate, this is controlled by the P ATTR parameter in position 60.
Add an N to this location and the presort will receive the Nonprofit rate.
