Amazon Bucket - One file per domain in a time-stamped directory?

I didn't see any documentation on using the backup features on amazon bucket (at least within virtualmin itself), so I'm having a hard time figuring out how to:

1) Backup one file per domain
2) Have each backup session create a time-stamped subdirectory to put all the backup files in

Is this possible, and if so, can it support the new auto-delete feature of old backups too?
