Do you want to open links in a new window by default?

Question

TinyMCE

Hello.
I'm using Wordpress 4.7.4 It is
necessary that links open in a new window by default when inserting/editing. Those. to add 'target = _blank'.
How to add checkbox 'Open link in new tab'( https://i.stack.imgur.com/1b8TM.jpg) when you select 'Link options' ( https://i.stack.imgur.com/rpCiq.jpg) I figured it out.

function ahu_after_wp_tiny_mce() {
    if (get_post_type() == 'post') { ?>
    <script>
      jQuery(document).on('wplink-open', function (wrap) {
        if (jQuery('input#wp-link-url').val() <= 0)
          jQuery('input#wp-link-target').prop('checked', true);
      });
    </script>
    <?php
  }
}
add_action( 'after_wp_tiny_mce', 'ahu_after_wp_tiny_mce' );

But if you do not select 'Link options' when inserting/editing a link, then 'targer=_blank' is not added.
Please tell me how to do it.
Thanks in advance.
