apache: redirect only 404 error messages to a different log file in httpd.conf

apache: redirect only 404 error messages to a different log file in
httpd.conf

After a bit of searching, I couldn't find a way to redirect only 404
specific error messages to a different log file(not error_log). Please let
me know if there is way to achieve this. Quick help would be appreciated.
Thanks in advance. :)
