App Icon Per Configuration

Is there is a way to set the App Icon per configuration in the Projucer? I would like to have a different icon per release type (dev, beta, public), but am coming up short on how to accomplish this with the projucer. When using the asset catalog in XCode, you can do this in the Build Settings, but with the projucer it seems to be limited to the exporter. Any advice on how to accomplish this same mechanism?
