In the meantime, another simple approach might be to store these csv files in an s3 bucket and add an Athena table reading these files. Then, from QuickSight, use that athena table in your dataset rather than uploading the files there. (Assuming you don’t use Athena partitioning, then newly updated files’ data will immediately be visible to QuickSight - but will need a SPICE refresh if you are using that)
