Scatter Command

When building with stone for example you would mix in other similar stone to add details but to do this on a large scale by hand can be very time consuming so there should be a scatter command. Similar to the /FILL you can do a command to scatter a block of your liking onto a build in a certain area. Could be something like /Scatter Mossy_Stone_Brick ~15 ~15 ~15 ~~~ Stone_ Bricks 0
