How to deploy a .xml as part of a Available Application install?

Hi Tech Community,   

I am trying to create an application to be available in Software Centre.   I have created the application in config manager and have made it an Available deployment to my user base.     

The application displays in Software Centre & installs/uninstalls correctly however as part of the install I need to copy a .xml from a network location to the local computer. 

I am not sure on how to achieve this.  My first though was to create a Task Sequence however it doesn't let me create a deployment for Users only Devices.    

Any help/Suggestions would be greatly appreciated
