Possibility to derive Intended Use in Requisitions or Purchase Orders

Summary:

For a customer in Brazil with Oracle Fusion Procurement, the "intended use" field in the Requisition has an associated list of values with many options for goods and services, which can be manually assigned incorrectly.

This field can be used as a tax driver, mainly in Brazil. Is it possible to create a rule with the Tax Engine that allows to fill this field automatically in the requisition or purchase order?

In this case, the customer takes the data from the purchase orders and sends it to another system, so it would not be an option to create a rule to fill in the "Intended Use" field in Payables.
