LA/LV - Ability to save syslog/trap to a file using Custom Rules

Is there an option to save syslog/trap messages to a file, using Log Analyzer/Viewer custom rules?

I am thinking of similar functionality to older Syslog Viewer:

The only option I found is to forward syslog/trap messages to Orion alerting service and next to use "Save to file" action.
However this would generate insane number of alerts, so it is far from perfect.

Thanks,

Marcin.
