Starrocks 3.5.1 Using to store in S3

INSERT INTO FILES ("path" = "<s3://some_s3/filename.parquet>" ... )

it creates a subfolder called

"filename.parquet"

, even with the `"single": "true`" parameter there's no way to set the filename and create a single file with that filename? Thanks!

it is a path, file name is set by BE node

so, I cannot set the filename right?
