With Roguelike Dungeons, one of the configurations I used was to add Lycanite's Mobs creatures to the correct biome-related dungeon spawners. So, for example, I'd add Sutiramu to the list of spawners for desert dungeons. Digging through the datapacks, I was able to find monster/spawner (I think) definitions here, but there doesn't appear to be a way to customize those on a per biome basis. Is this something that didn't make it or is there some way to do that that I'm not aware of.

Yes, I'm aware that I'm probably a monster for adding Lycanites mobs to the spawners.
