Creating different color for immediate surrounding neighbors

I’ve been playing for a few years now and have come across many instances where neighbors come in to help, but are seen as enemies for various reasons. Why not creat a group where an officer can enter the names of surrounding castles as we do with Allie’s and have a color assigned to them.

Maybe for the number of castles owned you have that many slots for neighbors names. You can input all the names of neighbors that consistently come help. Tired of seeing help being trapped or killed because they are only seen as red.
