The general intent for INN logging is that you filter all of the logs into
separate files using syslog configuration and then only read the nighly
report, which should summarize any important information in the logs that
you need to be aware of. If you discard the "group" log lines, you will
lose the statistics in the nightly report about what groups are being
read; that's where that data comes from.
Regardless, I don't believe nnrpd supports customizing its logging in the
way you mention.
