How to choose a single project template from Multi project template

Hi,

I have create the project template for my MVC projects.

And also I have created the wizard for these templates. Now I have used the project templates names areMVC3Razor,MVC4Razor,MVC5Razor, MVC3Aspx,MVC4Aspx, MVC5Aspx. Right now I have used 6 templates for my MVCprojects. 

Now I have create one root template and other templates are copied into the root template location. I have created the wizard to get the project settings like MVC versions,View Engine. If we click the Version as MVC3 and View Engine as Razor then the template invoke the MVC3Razor project inside of the root template. 

The IWizardImplementation RunStarted method has automatically invoke the base template. But I need Dynmaically invoke the templates based on user selected project settings. 

Thanks in advance,
