Statements/Notices Letter Text - On Statement

In document 625781.1, adding text to the statement is shows as an option:

"Optional.  Set up letter text you wish to print on the statement in Statements/Notices Letter Text ((P03B2801).  This can be set up for statements in the same way as the letter text used for delinquency notices.  See Document 1490134.1 E1:  03B:  Setting Up Delinquency Notices and Fees (P03B2501, P03B2801) for further information."

I've read 625781.1 and 1490134.1 and have found very little information about how to print a small amount of text on statements.  We wish to provide contact information for our AR department.

I get as far as setting up the actual text in the P03B2801, but have no idea how this text is tied to the statement.
