Unfortunately, the only way to currently do anything similar to this is to login to the console via SSH and use the ftpput command to PUSH logs to an FTP server of your choice.

Ftpput doesn't always work depending on the target FTP server which support and I found so here's a little guide on how to use Curl as well: community.sophos.com/.../73466
