Question on RT at a glance customization

I am not sure whether this is an issue or by design for RT.

For our current configurations, as a privileged user, I am unable to view the tickets I requested unless I do a search for the tickets. Is there a way to show “Open Tickets” and “Closed Tickets” in addition to “10 highest priority tickets I own”? In additional, is there a way to do a global setting for display columns in the pane? The only way I know is for users to customize themselves through the Edit button. Here are the current configurations of our RT:
