Need view or scrollview depending on platform

I have a container (currently a view) that needs to be a scrollview if running on android. Rather than create 2 controls with platform specific tags like the following:

<View id="container" platform="ios">
//Lots of children controls
</View>
<ScrollView id="container" platform="android">
//Lots of children controls
</ScrollView>

I thought I have seen a way in alloy to reference a commonjs module that can return a ui control. So hopefully I can just call one module, perhaps a commonJS file that would return the correct UI control. Something like:

<Require src="viewByPlatform">
//Lots of children controls
</Require>

And in the viewByPlatform file it would either be an xml file or possible a commonJS file that returns a view or scrollview depending on platform. Is something like this currently possible?
