is it possible to name a file using current process id using a File Appender?

[Barvaz Barvaz]

Hi,

I'd like to configure a file appender, naming the file with the current
process ID (windows environment).
For instance, if the current process' ID is 1234, I'd like the log file to
have the name mylog1234.txt.
I know it can be done programmatically (by code), but I wonder, is it
achievable through configuration file?

Thanks!
