Sorry, just noticed this request. Structure allows adding custom fields as columns. So the task here would be to create a field that displays the required URL. There are a couple of add-ons allowing this kind of flexibility, including ScriptRunner.
Hopefully this answer is useful.
Let me add another two cents, Randy,
If your goal is just viewing pages linked to the issue, then I suggest trying Structure.Pages add-on
This will allow listing all the pages as children of items in your structure, and viewing them with one click.
