Add transaction rid, generated timestamp or any other uuid to each imported file from S3/directory

Question

in the Foundry Data Connection app, I can apply Transformers to the files ingested from S3 or any other Filesystem like source.

Is there any Transformer available to add an identifier (e.g. current transaction_rid, a generated timestamp when the ingestion started, or a uuid) to all filenames?

We have a source that provides numbered files, that get deleted automatically and replaced with new version, but we want to leverage an APPEND/UPDATE transaction type in the ingestion.

Thanks
