Voice control using aggregate inputs

I believe there may be a problem with voice control. It's seems that it cannot accept input from an aggregate input. I have created an aggregate input using two microphones and it seems that they are working properly. I can record voice memos and in the sound settings the input level changes appropriately with the sound of the environment, but the voice control features are not working. At first when you first add the aggregate device, voice control does not see the new input until you restart the Mac but even after you restart, it doesn't seem to actually work even though it does see the input after the restart.
