Hi.  
I would like to specify a file extension that should be read by logstash.  
Below my config that I've tried and it's not working.

```
input {
  s3 {
    access_key_id => ""
    secret_access_key => ""
    bucket => "logs"
    prefix => "dx/*.log"
    type => "aws-logs"
  }
}

```

is there any workaround how to achieve this?  
Thanks!
