Let players make wandering trader walk along a certain path.

Hear me out, let's make it so that (in creative) you can make wandering trader or maybe even the bedrock NPCs walk along a path you can select. They way it'd work is that you would shift+right click a wandering trader (or NPC) and then an interface would open up. So you click a starting point for the path they would walk along, then add points (by right clicking) they walk to every 10 blocks or so, but you could do less or more. Then you either select a end point or make it loop by selecting the starting point. This would be very useful for mapmakers like me. They would let you make you world fell alive. I'm tired of having a city full of villagers and traders right next to another one and have to tell people its supposed to have trader walking to the cities. Also, they're wandering traders, not just random stroll around a 5 block circle traders.
