Is it possible to preserve chain of custody metadata in S3 exports from BYOC?

Context: We are using the Bulk Export API to pull digital channel recordings from a BYOC S3 bucket for legal discovery. The exported files arrive in our destination bucket, but the original object tags containing the recording timestamp and agent ID are stripped during the transfer.

Question: Is it possible to configure the export job to retain these specific S3 metadata tags to ensure our chain of custody remains intact?

make sure you check the bulk export documentation for the latest metadata handling options. it usually strips custom tags by default, so you might need to use a lambda trigger on the source bucket to copy them over before the export job runs.
