Hi Kevin
I think this is more of a Joomla! funcitonality rather than a template issue.
Yes, from what you’ve explained you will need to “clone” the article and publish it to the correct categories/sections.
I’m not saying that it is not possible to do (unless you’re very efficient at hacking the core joomla files), but it may be worth registering a request at Joomla!’s forums (http://forums.joomla.org) where the developers can actually see that this is something users would like.
You may find an extension that does what you require at http://extensions.joomla.org – however, you may or may have to pay for something that does what you require.
Last but not least, if you can’t find anything that suits your requirements and you have some cash available, you might be able to recruit a joomlancer (http://www.joomlancers.com) that can customize your website.
Hope this helps. I know it’s not the actual answer to your problem but as mentioned before, it’s an actual Joomla! functionality issue.
