Hello! Is it possible to use different credentials for different s3 buckets on different hosts?

When I try to do like so:

s3 {
            region: "us-east-2"
            key: "***"
            secret: "***"

            credentials: [
                {
                    host: "my_own_minio_s3_api_host:port"
                    secret: "***"
                    key: "***"
                    bucket: "specific-bucket"
                    secure: false
                }
            ]
        }

I got this error:
Could not list/find remote file(s) when adding None

But it all works good for the "general" creds.
