每周或每月旋转日志，而不是每天

I've just found the rotating_file type option for the monolog channels which will handle the rotation of the logs daily.

I'd like to rotate my logs weekly instead, but I can't find any info about it. Looking at the github project it seems that the possibility it at least contemplated:

class RotatingFileHandler extends StreamHandler
{
    public const FILE_PER_DAY = 'Y-m-d';
    public const FILE_PER_MONTH = 'Y-m';
    public const FILE_PER_YEAR = 'Y';
    ....

Is it possible?
