Angular2 + import of ng2 material

I use angular 2 with ng2 material to display radio and flag components, in each component I see that I need to import all the contents of ng2 material and finally use only one component

=> result, it charges my application and makes it slower.

I want to know if I can import only the component that I need, despite the fact that in the documentation for the ng2 material they import all of them.

import {Component} from 'angular2/core';
import {bootstrap} from 'angular2/platform/browser';

import {MATERIAL_DIRECTIVES, MATERIAL_PROVIDERS} from "ng2-material/all"; <<<<<

import {ROUTER_DIRECTIVES} from 'angular2/router';
import { CORE_DIRECTIVES, FORM_DIRECTIVES } from 'angular2/common';

@Component({
    selector: 'radiobox',
    templateUrl: '/radiobox.html',
    styleUrls: ['radiobox.css'],
    directives: [MATERIAL_DIRECTIVES] <<<<<<
