You cannot using Tabview. You are supposed to be able to using Tabber. However, the feature is buggy and doesn't actually work as intended.
Actually, it looks like they fixed the bug since I last checked. So you can do it using Tabber but not Tabview. If you choose to switch, note that Tabber uses a different syntax and does not permit you to choose the default tab. Also, you should make sure that none of your Tabber tabs share a name with any of your article headers. The two use the same system and having two things with the same name sharing the system will cause one of them to not work properly.
