WorldEdit-esque random block pattern?

[NyanSwagCatCC]

Hi, I'm trying to create some organic patterns on my map, and I'm wondering if there's a way to do fills of assorted blocks like WorldEdit. (e.g. //set stone,diorite,andesite,granite)

Anyone know a command that can do this?

Alternatively, use

/brush random stone wood leaves dirt etc

Then proceed to build normally with /z
Beware: /abort will reset your current brush.

/z random [blocks or block ids (ex: stone stonebrick lava air)]
