Add "Side" 'Context' options for displaying Metaboxe in admin comment edit form

Hi,

I try to add metadata to worpdress comments, so i would like add a metaboxe in Admin comment edit form on the right sidebar, or I can just add it in “normal’ context…

My current solution involves modifying the wordpress edit-comment-form.php file in wp-admin folder to add the following code :

<?php
  do_action('add_meta_boxes_comment', $comment);
  do_meta_boxes(null, 'side', $comment);
  ?>

But I would like keep this core file clean.

Is it planed to add this to the next realease ?
