Includes in global javascript node

Is there a way to 'include' multiple global javascript files?

I know I can use 

`<Include file="MyGlobalJavaScript.xml" />`

to include a self-contained global javascript section, but what I would like to do is

```
<GlobalJavascript>
<Include file="SomeGlobalJavaScript.xml" />
<Include file="MoreGlobalJavaScript.xml" />
</GlobaJavascript>
```
