How can we update data in multiple columns of the Cost Sheet simultaneously using the REST API?

We are currently updating data in the Cost Sheet columns via the REST API using the following method, which allows updates to only one column at a time:

Method: PUT
URL: /ws/rest/service/v1/cost/columndata/project_number?columnname=PAT Budget (Final)

We are seeking a solution that enables updating multiple column values in the Cost Sheet simultaneously through the API.
