Create Multiple Project Task Rate Overrides on a Bill Plan

Hi All,
We are adding Multiple Expenditure types on the Bill Task Rate Overrides on a Bill Plan for a Contract Line in Fusion. However, the current API supports only adding one single expenditure type at a time and does not support an array structure where we can process multiple expenditure types through a single API call.

This limitation is significantly affecting our integration processing time, as we typically have 100+ rate overrides per Bill Plan of a Contract, and sometimes even more when different effective dates are involved.

We would like to check if anyone has faced a similar limitation and whether there is an alternative or recommended approach to handle this use case efficiently.
