Yes!

We added a log extension mecahnism a while ago.  Here's a snippet you 
could start from...

```bro
option my_server_name = "";

type MyLogExtension: record {
         server_name:   string &log;
};

function add_my_log_extension(path: string): MyLogExtension
         {
         return MyLogExtension($server_name = my_server_name);
         }


redef Log::default_ext_func = add_my_log_extension;
```
