More Than One Error When Uploading Archive?

Is there any way to get more than one error message at a time when uploading an archive to the App Store from Xcode? It's bad enough that the messages from Validate are virtually worthless, but having to rebuild, re-archive, choose "Distribute App", and re-upload an app over and over again only to find out that you are missing an icon of a particular size hours later when that could have been pointed out the very first time (or even before any of the building, archiving, or uploading took place) is darn frustrating and a huge waste of time.
