Describe the feature you'd like

As a Dike is tall pillar of materials, where you can add multiple of the materials into it, a way to limit some of the materials to only generate between some Y-levels could be a really good idea. Would allow to make a Dikes with a lot of materials in them, but some of them would only generate on lower y-levels, and some above some y-levels😄

For Example a dike with Iron, Gold and Diamonds in it, where iron would generate at the entire height of the Dike, Gold only between levels -20 and 60 and Diamond only below level 0

Additional context

Pretty much while thinking about ideas for a Dike, I found it impossible to balance them if you want some rare and common materials to be in one deposit, simply because if you set Diamonds as possible material along side Iron, both will generate on the entire height of the Dike, what is not great, as Diamonds at, for example, level 80 aren't a thing right 😅
