Assignment of different Dicument Type in Automatic Payment Program

Hi SAP Gurus,

Presently the payments are being handled centrally at Corp Office in a State. The payment method is C and the clearing doc type is KZ. Now the Company is also starting to use APP at another office in another state. The payment method is C only but for bifurcation purpose of line items the clearing doc type is to be BB which is havng a different number range. But in FBZP, system allows one doc type which is to be entered in Payment Methods for country. Is there any way in which I can do this?
