You can absolutely do this. I haven't played with it in a while so I don't recall if that got put behind the service paywall. The wake word is processed local though and the software is open source so absent the online management dashboard I'm certain you can hard code it. They were also working on, or had, a home server for managing your devices entirely internal to your network and it seems unlikely they didn't include a way to manage the wake-word.
