[syslog-ng] keep_hostname as source option

I All, I saw this post related to keep_hostname option: https://lists.balabit.hu/pipermail/syslog-ng/2002-November/004075.html And I'm wondering if there is now a possible keep_hostname usage as a non-global option (which would override the given global option) ? A bit as given here: source syslog { udp( port(514); keep_hostname(no); ); }; Thanks in advance, Regards, Joël
