Eigentlich eine gute Idee für den Import, aber bitte vorher genau durch diskutieren.
Ein Import nur mit Gebäuden halte ich für nicht ausreichend, es müsste unbedingt die volle Adresse angefügt sein. Sonst sinkt die Bereitschaft nachträglich Sachen dazuzufügen oder zu ändern.
Ich will nicht "meine" Orte komplett überarbeiten müssen!
