Mapping Payroll Elements to Pre-existing Third Party Organisations and Payment Methods

We need to create a number of new payroll elements to drive payroll deductions from employees and pay these over to a third-party organisation. We have the Third Party and Third Party Payment set up and currently make payments via BACS through the payroll process for a number of other third parties. This was set up by our Implementation Partners.

How are new payroll elements mapped to existing Third Party Payees and Payment Methods, so we can use the payroll process to similarly pay those third parties via BACS? I'm unable to find any guidance notes from Oracle for the configuration steps.
