How to handle payments to individuals/beneficiaries without creating them as regular suppliers

Summary: We are implementing Cloud ERP for a multi-lateral agency that need to process payments to individuals (non-employees and non-suppliers) on regular basis. These payments are in the nature of transferring the benefits, such as scholarships, social payments, educational fees, honorarium to guest teachers, fees to conference speakers etc.

Procurement/Supplier Management team dont want to create these individuals as suppliers, as these do not fit into the defintion/qualification for suppliers. We cannot create them as employees or contigent workers as these are not part of the workforce. however, considering the payments will be processed frequently/regularly (different amount most times), we need to maintain and control the bank accounts in the system. We are happy to create stand alone or non-matched AP invoices for payment, however not sure how to store the master data pertaining such beneficiaries.
