Hi,

I am trying to read AWS cloudtrail logs stored in S3 bucket in the below folder structure  
`AWSLogs/accountnumber/CloudTrail/region/year/month/day` and send the processed files to the backup S3 bucket using s3 `backup_bucket` option. But I want to store the backup files also in the same folder structure, since there will be lot of regions i cannot create individual config file for each region. Is there any way to get the region dynamically and use it in backup\_add\_prefix option?

Thanks
