Filter and Store Windows Security Logs for 30 days?

Hi, I was wondering if someone could help with creating actions to store Windows Security Logs for  a 30 day retention period?  Could I have the server name at the beginning of the file, keep one log file per server, and have it contain the last 30 days of activity.  I know that it will likely require the Log to File--> Insert Auto-Split Value feature.  We have the full version of Kiwi.

Thanks!
