I've seen how to override module templates from other modules and theme templates from subthemes, but how do I override module from subtheme? The file is under the profiles folder.
Edit:
I'm using Open Atrium. I want to override this file:
/var/www/openatrium/profiles/openatrium/modules/apps/oa_home/oa-home-default.tpl.php
From my subthem wich is located at:
/var/www/openatrium/sites/all/themes/my_radix/
The subtheme is working fine, but I need to override some .tpl.php files that are not part of the parent theme. How can I do that? Where do I copy them? How do I tell Drupal to use the new files?
