Make storage deletion of achievements_locked() optional

Hi all,

Is there a way to NOT remove all storage data when an achievement is taken away?

I'm asking this because I've encountered an issue as described in the following:

USE CASE EXAMPLE:

• users gain achievements after 5, 50 and 100 comments
• suppose a user has already gained the "posted 5 comments"
• suppose a moderator, for any reason, have to delete last (the fifth) comment
• the "posted 5 comments" achievement should be automatically removed, but the total comment count should not be resetted (in this way, user can re-take the achievement posting another "fifth" comment)

To do so I've implemented hook_comment_delete:

function mymodule_comment_delete($comment) {

      // decrease comment count 
      $current_count = achievements_storage_get('comment-count', $comment->uid) - 1;
      achievements_storage_set('comment-count', $current_count, $comment->uid);

      foreach ( array(5, 50, 100) as $count ) {
        if ( $current_count == $count - 1 ) {
          // re-lock achievement:
          achievements_locked('comment-count-' . $count, $comment->uid);
        }
      }

}

but the code above doesn't work because achievements_locked() removes all storage data and "comment-count" is resetted. All user's previous comment count is lost.

Please give me some advice to reach the goal (or is this a feature request?)

Thank you very much
