shortcodes with directory listings

Hi, using google maps plugin generates a shortcode.

In 'directory' the dr_listing does not evaluate shortcodes (I assume this is deliberate?).

Is there a hook that can be used
e.g. as we can turn on short codes in excepts with

add_filter( 'the_excerpt', 'do_shortcode');

is there something like

add_filter( 'the_dr_listing', 'do_shortcode');
that we can hook shortcode processing too
