Can we pass locator in the Create Supply Order Rest API

Summary:

In the pay load for creating the Transfer order using Supply Order Rest API, we can give Source organization and source subinventory. But we would like to go one level below that, by providing the source locator too? Is this possible.

When I try to use "LocatorName" or "SourceOrganizationLocatorName", Postman throws the error "Invalid Attribute" as shown below. I would appreciate any feedback.

Rest API: /fscmRestApi/resources/11.13.18.05/supplyRequests
