Make a specific controller grab views from a subfolder

Let's say I have a base controller class named Foo and an instance of this controller named Bar.

I need Bar to search for views in the following folders:

~\Views\Foo\Bar
~\Views\Foo\Shared
~\Views\Bar
~\Views\Shared

But I want other controllers to work same as before, which is to look for views just in:

~\Views\ControllerName
~\Views\Shared

Is it possible to achieve in asp.net-mvc?

The solution doesn't have to be clever enough to know that the base controller class is named Foo.

It's kind of dirty approach, but you can try this in your Base Controller (Foo):

protected override void OnResultExecuting(ResultExecutingContext filterContext)
{
    if (filterContext.Result is ViewResult)
    {
        foreach (var engine in ViewEngineCollection.OfType<VirtualPathProviderViewEngine>())
        {
            var newViewLocations = engine.FileExtensions.Select(ext => "~/Views/Foo/{1}/{0}." + ext).ToList();
            newViewLocations.AddRange(engine.ViewLocationFormats);
            engine.ViewLocationFormats = newViewLocations.ToArray();
        }
    }

    base.OnResultExecuting(filterContext);
}

protected override void OnResultExecuted(ResultExecutedContext filterContext)
{
    if (filterContext.Result is ViewResult)
    {
        foreach (var engine in ViewEngineCollection.OfType<VirtualPathProviderViewEngine>())
        {
            var removeViewLocations = engine.FileExtensions.Select(ext => "~/Views/Foo/{1}/{0}." + ext).ToList();
            var removedLocations = engine.ViewLocationFormats.ToList();
            removedLocations.RemoveAll(x => removeViewLocations.Contains(x));
            engine.ViewLocationFormats = removedLocations.ToArray();
        }
    }

    base.OnResultExecuted(filterContext);
}
