General Nests

Hi, I’m doing a new map and want RockDrake and Magmasaurus to spawn nests in specific regions (RockDrake in a Moon Like Biome and Magmasaurus in the LavaBiome). Anyone have a way to fix that?

Obs: I’m still new to the dev kit, but in Rock Drake Graphs I see that the nest are only spawner in a place with the tag “DrakeNestSpawns”, do someone know how to make a place with this tag, or some other way to make it happen?
