How can I add EZ Pages to the 'Information' menu?

I have edited the title of the Information sidebox to read 'Main Menu' and I would like to add my EZ Page to that menu.

I suppose I could go the other way and create EZ Pages with relative links to each page then hide the 'Information' menu. Which I might do anyway so that I can use the top feature of EZ Pages as a horizontal menu.

Here is the site: https://www.paintingbarn.com - We have several more paintings/products but I haven't migrated them over to this new installation of ZC yet.

I was forced to upgrade from the previous site which used Drupal for the front door presentation but my Drupal install couldn't function on the newer 7.2 version of PHP. So rather than rebuild the Drupal/Zen Cart combination, I have installed a new version of ZC and will now use it for all pages. You'll see the Calendar page (CSS is yet to be polished) which is one of a few custom pages that will need to be added.

Thanks in advance!
