Working with project template

Hi,

I have a project template with multiple projects inside it. I want to add a single project to solution when i am trying to add New project from Solution explorer.

(right click on sol and add -> add new project).

Some thing like this

My target project template has proj1 and proj2 and when i am trying to add new project to existing solution my project template should pick only one project out of my project template (conisdering new project will be the required project instead of creating two projects).

Please explain how to achieve this behavior?

Thanks in advance.
