Serilog logger configuration by SourceContext

I am trying to implement serilog in a little sample-project. I´ve did the following so far:

My question:

Is there a possibility to configure two different loggers, based on CategoryName (in my case "MyLogger")? I want this logger to use a different file, than my default-logger. In my happy-world-fantasy it would look like: 

        Log.Logger = new LoggerConfiguration()
            .MinimumLevel.Debug()
            .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
            .Enrich.FromLogContext()
            .WriteTo.File(new CompactJsonFormatter(), @"C:\temp\standardLog.txt")
            .WriteTo.File(new CompactJsonFormatter(), @"C:\temp\specialLog.txt").Filter.ByIncludingOnly(x => x.SourceContext("MySpecialLogger")
            .CreateLogger();

And if I create a new Logger var logger = _loggerFactory.CreateLogger("MySpecialLogger"); the logs will be safed in my specialLog.txt-file.

Any ideas?

You need Serilog.Sinks.Map for this.

dotnet add <PROJECT> package Serilog.Sinks.Map -v 1.0.0-dev-00012

Then:

    Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Debug()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
        .Enrich.FromLogContext()
        .WriteTo.Map("SourceContext", null, (sc, wt) =>
            wt.File(new CompactJsonFormatter(), sc == "MySpecialLogger" ?
                @"C:\temp\specialLog.txt" :
                @"C:\temp\standardLog.txt"))
        .CreateLogger();
