"requires" value as variable in build?

Hi,

Suppose I have a class:

var requireClasses = ["first", "second"];

Ext.define("MyApp.view.navigation.Navigation", {

extend: "Ext.panel.Panel",

xtype: "navigation",

requires: requireClasses

});

And I noticed that classes, presented in variable "requireClasses" aren't placed in ExtJS 5 build file "app.js". Are my observations correct? I have a need to generate "requires" value dynamically. Is it possible?
