Include vstpresets on external drives in Halion 5 MediaBay?

Is there any way to make the Halion 5 MediaBay aware of vstpresets that are stored on external disks? Cubase MediaBay handles this, and the presets show up in searches. I haven’t been able to make this work in the H5 MediaBay, but hope it’s possible.

I’m specifically interested in “VST3 presets with samples”.
