OTM - Enable case insensitive on fields

Summary:

We need an option where we can automatically change some values ​​received by the REST API from lowercase to uppercase.

Is there any option (property, agent, etc.) that we can use to solve this problem?

Content (please ensure you mask any confidential information):

We currently have REST API integrations where, for example, the value in the location_name field of the location table is entered in lowercase (it comes from the source). And it stays that way.

In the OTM system logic, we enter this value as the shipment reference number for the supplier name in the shipments. As an identifier.
