CC Libraries in PowerPoint — how to place as vector?

I'm delighted that Adobe offers a way to bring graphics from my multiple CC libraries into PowerPoint. While right-clicking any graphic within the CC libraries panel and selecting "Place Graphic" works as expected, selecting "Place as Vector" does not. This is unfortunate, as most elements in my CC libraries are vectors (and I want to preserve them as vectors within PowerPoint). Has anyone successfully gotten this to work?
