Looks like I can add an Meta Desc column on custom post types, but not on custom taxonomies. Can that be added? I am using the Meta Description as the displayed excerpt for my custom “series” taxonomy and it would be great to be able to edit those short descriptions from the admin list page instead of having to click through to each term.

This is the code I’m using for the display of those fields if it helps:

$meta   = get_option( 'wpseo_taxonomy_meta' );
if (!empty($meta) && isset($meta['series'][$series_term->term_id]['wpseo_desc'])) {
  $desc  = $meta['series'][$series_term->term_id]['wpseo_desc'];
  echo '<div class="series-description">' . $desc . '</div>';
}
