HaHa! I'd be happily content to be a mere "guy who assembles stuff" in this case if I could find the right parts to assemble!
I guess I made a mistake is assuming that you were at least a diligent searcher, and that the "right" part didn't exist.
So, after confirming that it doesn't exist, or at least is so well hidden that you'll never find it, you can resign yourself to looking for trees, or try to come up with a workaround. For my part, I've always been willing to seek trees when needed, but take it that you'd rather not, hence your OP.
