Can we set a material in a data group item.
2 examples.
Toilet - Color - White, Beige, Purple - I believe it would have to be a pull down or selection of parts.
Wall - think layer of paint or gyp with paint - This one gets real gnarly with all the finishes and colorsand youd have to add another part to the gypsum or maybe everytime you create paint you start with the assumption that it is gyp bd with paint. I don't know without nesting it gets very ugly.
