Different Log Level per Logger per Appender?

[Dan Bress]

I am curious if log4net supports the concept of having the same appender 
associated with more than one Logger, but at different levels for each 
Logger.

Example:
Lets say I have Logger L1, and Logger L2
Lets say I have RollingFileAppender A1, and ConsoleAppender A2
Is it possible to configure log4net such that
L1 and L2 both send debug or greater to A2
L1 sends error or greater to A1
L2 sends fatal or greater to A1

I suppose this can be done by declaring two nearly identical instances 
of the rolling file appender, and setting a different level evaluator 
for each, but this seems like unnecessary duplication.

I am coming from the log4j world where I though this feature was 
supported, but i could be wrong...

Thanks,
Dan
