I want to give add an order digit on to the dashboard feed like in the image below:

I edited default-widgets.php - function wp_widget_rss_output () but it's still not showing any changes.
PS: I'm using WPMUDEV Dashboard Feeds plugin. This plugin changes the widget_options so that I can show my own RSS feed and not the default Wordpress ones!
