Change OpenSearch Fields within Zero-ETL Integration to OpenSearch Domain

I have created an OpenSearch Domain Zero-ETL Pipeline and I'm wondering if there is a way within the pipeline script to change the field names within OpenSearch from the DynamoDB.

So is it possiple to change say a field within DynamoDB from 'name' and have it within OpenSearch to be 'FullName'?

I'm using the AWS-DynamoDBChangeDataCapturePipeline
