Pkg exim4 users - Feb 2012 - begin local_scan in split confg

Hello. Where i have to add section:

begin local_scan
 kas_connect_to = tcp:127.0.0.1:2277
 kas_connect_timeout = 40
 kas_data_timeout = 30
 kas_default_domain = localhost
 kas_filtering_size_limit = 500
 kas_on_error=accept
 kas_log_level=3

in split configuration?
If i add it to /etc/exim4/conf.d/main/00_exim4-config_local_options at the end
of file, i have a error:

update-exim4.conf.template -rn && update-exim4.conf
2012-02-12 12:27:44 Exim configuration error in line 115 of
/var/lib/exim4/config.autogenerated.tmp:
  local_scan option "exim_path" unknown
Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not installing
/var/lib/exim4/config.autogenerated.tmp to /var/lib/exim4/config.autogenerated

I try add this section at the end of /etc/exim4/exim4.conf.template - and it is
works. But how to add it in split config?
