Split or Organize Backups by Domain

[hspcd]

Is it possible to modify Zimbra so that the backups are organized by domain? An example of the output would be:

/path-to-backups/sessions
./sessions/domain-A.com
./full-XXX
./incr-XXX
./sessions/domain-B.com
./full-XXX
./incr-XXX

This would make it much easier for us to have various SLAs in place on a per domain/customer basis, and it would help split the backups into smaller chunks to allow us to stream to tape more efficiently.

Thanks,
Clay
