more buildings should require two or more materials

Currently there are only a few buildings that require two or more materials to construct.  High pressure vents require metal and plastic, for example.  I'm of the opinion that more buildings should follow suit.  Solar panels currently require glass when they could also require metal.  Comfy beds require plastic when they could also require reed fibers.  These two examples are later game buildings, so more stringent requirements to be build them seems fair.  This would also be a nice opportunity to increase demand for lesser used materials like the aforementioned reed fibers.

I do hope they start adding more like this, I know at the moment it is very limited, but perhaps this is only due to the game still being early. We only recently got Refined Metals en masse and plastics
