Citi bank as vendor Payment advice in Text format

Hi SAP Gurus,

My requirement is, our client”s vendor is Citibank, out client’s employees will be given CITI Bank credit cards they use credit cards while they are in travel and after they return they submit their travel expenses statement in concur, from concur to SAP data will come through PI and vendor invoice document will be posted in SAP when we run F110 payment advice to vendor (city bank) should be generated in text format and should be placed in AL 11 directory PI will move the payment advice file to city bank.

please note: my client bankers are different, but payment will be made to Citibank as a normal vendor not as banker.

please note that there is payment advice form already assigned at paying company codes in FBZP so can we assign once more form at same level or should we use New payment method for assigning new form to get vendor payment advice in Text format please advice me.

Thank you very much for your help and support.
