how to change the default route in nopCommerce

Question

I am using nopCommerce, I want to change my default route from Index to another ActionResult Promotion which is also present in same HomeController, I have done these following tricks, but no solution,

in Nop.Web\Infrastructure\RouteProvider.cs

 //home page
            routes.MapLocalizedRoute("HomePage",
                            "",
                            new { controller = "Home", action = "Index" },
                            new[] { "Nop.Web.Controllers" });
            //for promotion
            routes.MapLocalizedRoute("Promotion",
                            "",
                            new { controller = "Home", action = "Promotion" },
                            new[] { "Nop.Web.Controllers" });

in Global.asax

 routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "Promotion", id = UrlParameter.Optional }, // changed to Promotion
                new[] { "Nop.Web.Controllers" }
            );

I found the solution by just adding value Home as url name in default route, I wounder I changed the Action as Index in Global.asax. This works fine.

//home page
            routes.MapLocalizedRoute("HomePage",
                            "Home", // added value in the default route
                            new { controller = "Home", action = "Index" },
                            new[] { "Nop.Web.Controllers" });
            //for promotion
            routes.MapLocalizedRoute("Promotion",
                            "",
                            new { controller = "Home", action = "Promotion" },
                            new[] { "Nop.Web.Controllers" });
