How to derive payroll SLA based on legal employer/legal entity and province

Summary: We have a requirement to derive segment values on payroll accounting based on legal employer/legal entity and province

Content (required):

Our client is currently using Cloud payroll. They are in the process of implementing ERP and are working on the processes to create accounting from payroll to the GL. There is a requirement to derive segment values based on legal employer/legal entity as well as province. However, I don't see any relevant attributes in the Payroll SLA to achieve this derivation.

I did attempt to derive the segment value based on the Transaction Legal Entity Identifier in Subledger Accounting but this didn't work as there is no legal entity id being passed into SLA on the payroll accounting.
