Recently I have seen (and rejected) many name changes on places where people attempt to change the name to one they would like to see as a shortcut name in their destinations.
Waze should warn them when they attempt to change the name of any place and provide an option to properly nickname a routing destination without changing the name everyone sees.
I usually send them a message via Chat when this happens and reject their changes, but it would be better if Waze did the warning .
