Create or update multiple Value Set Values in a file using REST API in Oracle Fusion

Requirement:

Process or update multiple Value Set Values for (lets say) a Project Numbers value Set in Oracle Fusion. We need to perform the action using REST APIs ONLY and not using SOAP webservice.

Query:

Is there a possibility to create/update multiple value set values using REST API, at once ? Can we process a list of value set values (to be created/updated) together in a single invocation ?

If so, please share the details, at the earliest.
