Do auto organize rules not work for Folder Portals?

I recently switched my fences to all be folder portals. I was super excited for this option because it fixed my biggest complaint with Fences -  when windows first loads, it takes forever for Fences to load, and during that time my desktop is covered with a million icons.

However, now that I have done it, I've discovered that it doesn't appear that I can set the auto-organize options to move documents and such into my new folder portal fences - only to other fences. This kind of makes the folder portals useless to me.

Is there a way to get this to work? Is anyone aware if this is a future feature?
