Custom Android Wear watch faces, how can I change more than the color themes and size of the hands?

Custom Android wear watch faces

I had a Samsung Gear and all the watch faces had multiple customizations. I now have a LG Urbane, only a few of the paid watches have customizations. Seems like all you can change are color themes and size of the hands.
On Samsung you could move the small dials around, change their properties and functions.
