Template in Visual Studio Shell Isolated

Hi, first of all, sorry for my english.

In the Isolated Shell application I want to add a template, if that's possible. Am I right?. If you can help me or refer to somewhere that provides this information I would appreciate it.

I have the example of IronPython VS2010 Isolated Shell, but I don't understand how it works very wel.

Thank you very much.
Fabiana.
