The product department informed me that it can receive national and international stations either using the DAB+ system or by connecting it to the internet. However, there is no option to save directly to the receiver. However, there is an app that also allows it to connect with the phone to transmit music via Bluetooth. That app should allow you to save stations.

The app would be this one: https://play.google.com/store... or for iOS: https://apps.apple.com/lu...
