Write custom logs to file output?

Hello.

So we all know the good old “Print” that has a check box to Print to file whatever you want:

But when I open this log file, I can see that there are also other engine logs entries, which increases my log file, and makes it dirty.

I would like to have a file for my logs only, log my user actions so later another software can read and create statistics, like kills and stuff, even to decide to close a file and start another file if wanted (like a log per map/round)… would be nice if this file is not so dirty and heavy.

Is there a way to log in another file? to specify file name? Or is there a plugin for this purpose that already suits my requirement?

Any help is very welcome!
