How do I make Serilog overwrite previous log file on rollover?

The title basically. I want Serilog to overwrite the log file on rollover and not create log-001, log-002 etc. There doesn't seem to be any option to do that from what I see in the references.

Of course it's possible to query the file size and delete it if it grows too big. But is there any way to handle this from within Serilog?

Update: It was a rubbish answer, but with Nicholas Blumhardt's comment I think I can make it better

Check out FileLoggerConfigurationExtensions

 //   rollOnFileSizeLimit:
 //     If true, a new file will be created when the file size limit is reached. Filenames
 //     will have a number appended in the format _NNN, with the first filename given
 //     no number.

I think combining retainedFileCountLimit, fileSizeLimitBytes and rollOnFileSizeLimit you could get close to one file :)

The following configuration should produce 2 files:

.WriteTo.File(
   logFilePath,
   rollOnFileSizeLimit: true,
   fileSizeLimitBytes: 1_000_000,
   retainedFileCountLimit: 2))
