Biome Excluder Option for block spawning

The biome restriction feature is extremely useful when it comes to making blocks spawn in a few biomes. The annoyance comes in when you want a specific block to spawn in every biome or most biomes excluding a few, that you don't want the block to spawn in. It would the remove process of having to restrict a block to every biome except for the one you don't want it to spawn in. I think this feature would some people who focus on biome themed plants, or "forageables. " For example I am working on a (private) mod based off Stardew Valley. I am creating forageables like the ones in  the game. but the problem is some of the plants are spawning in the desert and mesa biomes. When that happens I have to restrict the spawning of said forageable to every biome except for those two, which takes a while because I have multiple custom biomes. Basically my feature request would be to have a Biome Excluder option below the Biome Restriction option to speed up said process. If there is another solution that I can use currently explain it below.

Anyways thanks for creating this modding software. It's been extremely helpful for me.
