npm debug can i invoke with multiple names

Question

Currently I am initializing the debug module by

import express = require('express');
import debug = require('debug');

var routeLogger = debug('myapp:routes:index');
var router = express.Router();
routeLogger('Start setting up index route');

I am wondering if i can put more than one name to the debug function? such as debug('myapp,routes,indexRoute')
