Is it possible to have a screen routing configuration for each module with Angular JS ? If possible, how to route between modules?

Question

var app = angular.module("app", ['ngMaterial', 'ui.utils.masks', 'ngMessages', 'toastr', 'ngStorage', 'ui.router']);

app.config(function ($stateProvider, $urlRouterProvider) {
    $stateProvider
            .state("Servicos", {
                url: "/Servicos",
                templateUrl: 'GED-ME-Tamplates/Servicos.html'
            })
            .state("Acesso", {
                url: "/Acesso",
                templateUrl: 'GED-ME-Tamplates/Acesso.html',
                controller: 'AcessoCtrl'
            })
            .state("Cadastro", {
                url: "/Cadastro",
                templateUrl: 'GED-ME-Tamplates/Cadastro.html',
                controller: 'CadastroCtrl'
            })
            .state("VerificarDoc", {
                url: "/AutenticidadeDeDocumentos",
                templateUrl: 'GED-ME-Tamplates/VerificarDoc.html',
                controller: 'VerificarDocCtrl'
            });
    $urlRouterProvider.otherwise("/Servicos");
});
