Is there away to have vs2008 collapse nested classes?

Question

I'd like to be able to collapse (with the default chord ctrl+m, ctrl+o) the following

class Foo
{
    string Test { get; set; }
    string Test2 { get; set; }

    class Bar
    {
        string Test3 { get; set; }
        string Test4 { get; set; }
    }
}

To

class Foo
{
    string Test { get; set; }
    string Test2 { get; set; }

    class Bar ...
}

Right now there is no change. Any ideas on how to accomplish this?
