Block Variants

Hi

I'd really like base blocks (andesite, granite, diorite for example) to have the same variants such as sandstone, stone or such things
I'd really like for concrete to have at least stairs + slab variants, as I'm currently building a city which requieres lots of concrete, and I could really notice the transition between white concrete and smooth quartz slabs, you know ?
Please consider adding this in a following drop, not necessarily as a main theme, but rather as a secondary addition in order to not affect the schedule you might already have
Thank you
