It's Time to Organize the Doors and Windows

This is absurd. This is ridiculous. I've color-coded in this image different full sets, spread out from each other. The entire catalog is like this.

Ideas:
-Give each "set" a base object and you open it up to reveal sub-objects, kind of like how counters work. 
-Simply force items in the same set to appear next to each other?
-Refine the search tools so they can search for a keyword and display only items with that word- currently, they cannot do this in "build mode" i.e. when looking for doors or windows.
