Here's some helpful info on Named Location Volumes

I've learned that you can set Named Location Volumes (NLVs) inside of other bigger NLVs. For example, my Asymmetrical map has 2 main sides; Red vs Blue. Each side has a NLV named Red Wing and Blue Wing. Within those 2 named zones, I can set as many NLVs as I like to trigger a different named zone whenever you walk into them.

This is useful knowledge for those who don't want to have empty named zone spaces on their map, but don't want to make a billion NLVs to fill every nook and cranny either. So if you make 2 giant NLVs to separate the 2 halfs of your map in the beginning, then you don't have to worry so much about placing your NLVs so cramped together, because if a player leaves a NLV, it will still tell you which half of the map you are on; Red Wing or Blue Wing for example. Hope this helps anyone.
