Update (Project number and task number) expense type with itemization using REST API

Summary:

Need to update the seeded DFF fields(Project number and task number) with REST API in Itemization level.

GET - /fscmRestApi/resources/11.13.18.05/expenses/{expensesUniqID}/child/ExpenseItemization

While using the above API, we are not able to get the Project number and task number. But we can get and update the standard fields like Description and amount.

Is there any other API or child API to update (Project number and task number) expense report in itemization?
