Answer 1

If I understood your question correctly, you can create your own view engine which resolves view location at runtime and plug into your application.

Create your own custom view engine.

    public class MyViewEngine : RazorViewEngine
{
    public MyViewEngine()
        : base()
    {
        ViewLocationFormats = new[] {
        "~/Views/{1}/%1/{0}.cshtml",
        "~/Views/{1}/%1/{0}.vbhtml",
        "~/Views/Shared/{0}.cshtml",
        "~/Views/Shared/{0}.vbhtml"
    };

    PartialViewLocationFormats = new[] {
        "~/Views/%1/{1}/{0}.cshtml",
        "~/Views/%1/{1}/{0}.vbhtml",
        "~/Views/Shared/{0}.cshtml",
        "~/Views/Shared/{0}.vbhtml"
    };
    }

    protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
    {
        var catagoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.CreatePartialView(controllerContext, partialPath.Replace("%1", catagoryName));
    }

    protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
    {
        var catagoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.CreateView(controllerContext, viewPath.Replace("%1", catagoryName),masterPath);
    }

    protected override bool FileExists(ControllerContext controllerContext, string virtualPath)
    {
        var catagoryName = controllerContext.RouteData.Values["category"].ToString();
        return base.FileExists(controllerContext, virtualPath.Replace("%1", catagoryName));
    }

}

And register it here

protected void Application_Start()
{   
   AreaRegistration.RegisterAllAreas();

   RegisterGlobalFilters(GlobalFilters.Filters);
   RegisterRoutes(RouteTable.Routes);


   //Register your View Engine Here.
   ViewEngines.Engines.Add(new MyViewEngine());
}

Update route config, default should be

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{category}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", category = "DefaultCategoryName", id = UrlParameter.Optional }
        );
