Could also just make cellar walls impenetrable from the outside and do not allow any digging of exits to the surface or whatever.Well designed tunneling into enemy towns does sound tempting, probably not managable without being too strong though...
Edit: Actually my first suggestion probably still does not allow what was asked for. Maybe connecting cellars is just not a viable option then. I don't think it adds that much to the game anyway.
Impenetrable walls works well to. I like your suggestions.

And yes we agree connecting cellars creates headaches.
Good to see you posting Burgingham.
