How to remove year and month from Event permalinks?

I'd like to remove /YYYY/MM/ part from incsub_event permalinks. My customer has the same events usually (but not always) recurring yearly and wants to keep the same static URL for each individual event for maximum search engine comfortability.

How would you do this, Hakan? Current structure seems very hardcoded.

$event_structure = '/'.$this->_data->get_option('slug').'/%event_year%/%event_monthnum%/%incsub_event%';

add_filter "post_type_link" could be of assistance, because /event-name/ does get properly redirected by WordPress built in mechanisms, but /events/event-name/ throws a 404.

Thank you for any ideas.
