Let's say I have 50 person nodes and I set a new property like p.countryBorn = 'USA' for all. Later I notice 10 of person nodes actually are wrong and I need to update p.countryBorn value to 'Scotland'. How can I do that at once? I mean, I know p.name of 10 nodes, but I'm able to change one by one. Is it possible to set for 10 nodes at once?
