apache - Returning a 404 for a missing file under a specific directory -

in apache, possible in .htaccess return different 404 page based on filepath?

for example:

for missing pages under http://example.com/support/* redirect 404-support.php  else errordocument 404 /404.php

if have directory named 'support', put in .htaccess file inside directory , override configuration of parent directories. so, in / folder, specify be

errordocument 404 /404.php

but support folder, put in new .htaccess file , type in:

errordocument 404 /support/404.php
