Sometimes when I load a schematic, I would not like them being the default blocks. I would want them to be other blocks based on availability and design. For example. I would like to change all the quartz to stone etc., But the only way of doing this is to use schematic edit hotkey, but me being misclicky, it's not so friendly for me. The other way is to build in a creative world and then change every block and convert to schematic again, which makes me handle dozens of schematic for a single build.

I would like some kind of generic block like support. They should be easily configurable. The should have block properties like SolidBlock, FullBlock, TransparentBlock, Stair, Slab, PoweredByRedstone, StorageBlock, etc., This would be useful for building and redstone. And any block satisfying these properties would be able to placed without errors. It would also be nice if it had default block. And when pick blocked it should place match any matching block. It should have a nice ui in inventory to edit it
