Header Menu (primary) Trouble

Hi, I’m new to www.remarpro.com and the forums and developing an employee intranet site that is installed our our network server. We’re using Liquido Theme and Fluida Addons, but my trouble is with the WordPress Appearance, Menus for my primary Header Menu. I can successfully add page and custom links, but I would like to add an unclickable menu item with a dozen or more sub-items (to documents on our SharePoint library and to external web pages)…but here’s the kicker…I want those sub-items to come from a “link library” of sorts so that I can use the same list of links in different areas of our intranet and have one place where those links are updated or added to in the future. Is this possible and how?

I would appreciate as many ideas as possible to help me figure this out.
