Cushions should be placeable on themselves.

I was watching a video from Grian that went into detail about the uses of cushions, and it explained the process that is needed with snow for cushions to be placed. It showed how you can fill gaps on stairs and incomplete blocks by using snow to make layers, then replacing the snow with a different block to show only the cushions as if they were placed on each other.  I thought that can be so much easier and accessible to all builders no matter our patients or skill to be able to simply stack cushions onto themselves.
