Is it possible to have multiple 'standalone':s?

[tomsoderlund]

I'm trying to define two standalone:s in my Gruntfile:

browserify: {
	options: {
		transform: [['babelify', {
			presets: ['env']
		}]],
	},
	// The below standalone 'xp' IS available on window (window.xp)
	crossplatform: {
		src: ['crossplatform/index.js'],
		dest: 'app/scripts/crossplatform.js',
		options: {
			browserifyOptions: {
				standalone: 'xp'
			},
		}
	},
	// The below standalone 'myLib' is NOT available on window (window.myLib)
	myLib: {
		src: ['scripts/common/redux/index.js'],
		dest: 'app/scripts/myLib.js',
		options: {
			browserifyOptions: {
				standalone: 'myLib'
			},
		}
	},
},

Only the first one works, is it possible to have two or more?
