Template Shell Isolated and new language

Good morning.

First of all, sorry for my english.

I have a query with the theme of the templates in Isolated Shell, in the example of IronPython VS2010 Isolated Shell can not find where it's shown that load your templates. If you can help me or refer to somewhere that provides this information I would appreciate it.

What I want is create an IDE, i have an Isolated Shell application with VSIX Project for IntelliSense and another VSIX Project
for Syntax color. In the Isolated Shell application I want to add a template, if that's possible. Am I right?l

Thank you very much.
Fabiana.
