Edit Generation type

You know when we create a World, we can choose the Generation type, In Customizable World, We can select ore generation, cave size, water level, and a LOOOOT of things, Well I want this feature of Customizable World in our Custom Dimension(or even biomes), So in our custom Dimension, We can select Caves size, Amount of vanilla ores, and other options available in his feature

Btw, just found out, an Option for our custom to appear in this option, So we can control our ore generation as well but I think custom ores need a new Material type when creating block element type I think
