log files without date in name


I'm trying to use logrotate to keep the /var/log/mmdvm directory clean. I can not specify a simple log filename because each day the filename (before.log) changes with the date embedded. This occurs with MMDVM_Bridge, P25Gateway, and P25Reflector logs. Since these names are generated outside of logrotate, they are all treated as different logs. Is there a way to not include the date in the log file?
