Manually create supplier record for employees

We are implementing R12 in one country and converting data from 11i. We have many employee open prepayment records based on current process in that country. So instead of waiting for supplier record to be created in R12 when employee enters first expense report, we would like to create supplier record for employees using type - supplier used to process expense payments to internal employees (or whatever programmatic option available in API).

After we do that, will that be any issues in future sync of HR record to this supplier record? Or this linkage will be same as if we created supplier record using expense report export?
