How to use a Dynamic Data page template in a CreateUserWizard TemplatedWizardStep

Question

I am busy building an ASP.NET website that runs off a SQLServer 2008 backend database and I am using LinqToSQL and Dynamic Data. I use ASP membership for user registration. However I need to capture extra user information that is stored in other tables. I am using ASP's built-in controls i.e. login, change password, create user wizard etc.

Now, I want to add a templated wizard step to the create user wizard control to take on the extra information I need for the user registration process and I want to use the insert page template that is generated by Visual Studio (perhaps a customized one). The question is how do I point to the template in the wizard step and how do I get back after the user has completed the step? What must go into the "ContentTemplate" block in the code below?

<WizardSteps>
        <asp:CreateUserWizardStep runat="server" />
        <asp:TemplatedWizardStep ID="PersonalInfo" runat="server" Title="Personal Information">
            <ContentTemplate>

            </ContentTemplate>
        </asp:TemplatedWizardStep>
        <asp:CompleteWizardStep runat="server" />
    </WizardSteps>
</asp:CreateUserWizard>

Thanks.
