Improve the format of the rotation template by date

[KonovalovaKV]

Is it possible to add the ability to rotate by date so that you can specify not only the pattern, but also the path using the pattern.
For example: filePattern="logs/arch/{yy-MM-dd}/add/update.log"

Any news?

Sounds like a reasonable thing to want to do. I'd be happy to see a pull request for this, but it would make more sense for this change to be made on the streamroller library that log4js uses.
