I only care about one file in the sandbox and the organizer doesn't let me upload/download just that one file. I also can't find upload/download in the Xcode Applescript dictionary. The Xcode also only shows a subset of applications. My particular use case is that other developers have written apps using a library that I have authored. I then update the behaviour of the library for their needs based on interactions between the app and configuration for the library.
