This would be more of what you would learn in a live training environment. This type of thing would not be covered in the learning Center as it is way more complicated and requires code manipulation to do so. I can tell you that if you attent the CMS Expo in December you will learn this very thing in one of the sessions that is geared just for templates.
There will be some upcoming live training sessions in the Chicagoland area that are also going to cover some more in deapth training topics and they will be full day live classroom training available from
www.joomlearn.com so keep posted for that site to be launched very soon.
