Sculk Spreading Strength

As an experienced builder, the addition of Sculk blocks has been amazing in helping give my deep dark builds a more naturally spreading feeling. However, many blocks that I use are blocks that the Sculk cannot spread to. I would love to see a way to change how strong the spreading of Sculk is depending on the difficulty of the world. Or maybe a setting in game that changes what kinds of blocks the Sculk can spread to. This would be helpful for many map creators to come.
