How to update multiple transactions with a single REST API?

**This post was created as part of a How to Service Request (SR)

Release:

22B Patch 2

Summary of the question:

We need to update multiple versions of a quote in a single attempt and the action will be taken by the external website. OIC will receive this update, now OIC will be booked one transaction and cancel all the other transactions in set. Please let us know if there is a way to do all these updates in one go rather than invoking REST APIs for individual transactions.
