opening an app from an url + parameters

Now, i am using Flash pro to create my app, once packed it's tricky to mess up with the contents, is there a file i can edit, before rendering the app? for example is this something i can add in an xml file that is created in my app folder?

It starts with this:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

<application xmlns="http://ns.adobe.com/air/application/3.4">

    <id>appID</id>

    <versionNumber>3.0</versionNumber>

    <filename>filename</filename>

    <description></description>
