Add/Edit Alert -> Behavior -> Exclude Sites

I’m hoping you can help me with the exclude sites option under Behavior when adding or editing an alert.
My main site is example.com and my multisite sub-sites are example.com/subsite, example.com/subsite1, example.com/subsite2, etc..
On my site admin on the checkbox list of sites to exclude I see a list that just has example, example, example, but would rather see something that indicated subsite, subsite1, subsite2. Is there a good way to do that?

I found the code that displays the sites to exclude on site-alert-admin-manage.php starting at line 271
`<?PHP
foreach ($sites as $site) {
$site_name = explode(“.”, $site->domain)[0];
$site_id = $site->blog_id;
if(($action != “” && $action != “add”) && in_array($site_id, $excluded_sites)){
$checked = ‘checked’;
}else{
$checked = ”;
}
print “

• <span class=’name’><input type=’checkbox’ name=’exclude-“.esc_attr($site_name).”‘ data-name='”.esc_attr($site_name).”‘ value='”.esc_attr($site_id).”‘ “.esc_attr($checked).”/> $site_name </span>

“;
}
?>
