Install webapplication in a new web site?

How do I install a web application as a web site in IIS6 using the regular Web Setup Project? I do not want to install the application as a virtual directory in "Default Web Site", but a new web site (and if possible create the site during the installation).

Also, is it possible to s开发者_开发技巧elect the ASP.Net 4 Application pool as default in the setup wizard?

It's not possible.
