How to report 28% Backup Withholding on a 1099-MISC

I am in the process of trying to figure out how to report 28% Backup Withholding on a 1099-MISC.  After researching all day and doing some testing, I have yet to find anything on People Books or through Google searches saying specifically how to process backup withholding on PeopleSoft.  Looking for an idea of the correct way to handle this and maybe a "How To" document on setting up Withholding Rules.

Not sure if this is the correct way to handle this but ... I really think it begins with creating the Withholding Rules and how those rules flow over to the payment vouchers.  When playing around with the screens, I discovered that RULE0-Zero Percent Withholding Rule is the only rule that really exists for voucher lines making up the 1099 balance on a Vendor.  Is there any answer to create a RULE28 or something that withholds 28% of the voucher payment separately as a liability?
