This is a strange usage of the term "hardcoded", Normally, hardcoded
means that it is in the *code*, not a configuration file.

You would have to use a different class for that. I don't know one
offhand which implements the behaviour you want, but for example
TimedRotatingFileHandler switches log files after a configurable
interval. So for example
class=TimedRotatingFileHandler
when=H
would start a new log every hour (and rename the old log to contain a
timestamp).
You may need to write a handler which implements the behaviour you want.
Or maybe there is one on PyPi.
