Hmm, I don't know enough to give you a confident answer yet. However, I can share that the GCS source connector currently supports loading multiple non-compressed CSV files from a GCS directory [source](https://docs.airbyte.com/integrations/sources/gcs). For the GCS destination connector, it supports GZIP compression for output files [source](https://docs.airbyte.com/integrations/destinations/gcs). As for the roadmap, I found an entry about data type improvements for Generally Available destinations, including GCS, but it doesn't specifically mention the functionality you're looking for [source](https://app.harvestr.io/roadmap/view/pQU6gdCyc/launch-week-roadmap). For more information and updates, you can check the Airbyte documentation and roadmap: - [GCS Source Documentation](https://docs.airbyte.com/integrations/sources/gcs) - [GCS Destination Documentation](https://docs.airbyte.com/integrations/destinations/gcs) - [Airbyte Roadmap](https://app.harvestr.io/roadmap/view/pQU6gdCyc/launch-week-roadmap)
