However, we do have code to provide that functionality, it's just not merged. So you'd need to manually adjust your local confconsole code. It's also worth noting, that unless you lock the version of confconsole, any future updates that are installed will overwrite your changes.

The code that needs changing is in confconsole.py (see required changes here) and the netinfo.py (module of turnkey-pylib - changes here). It looks like it also requires you to write the domain to the inithooks cache file (within /var/lib/inithooks/cache).

Sorry that there isn't an easier way and it's not very explicit, but hopefully that's enough info to get you going?!
