Better support for aggregate devices on macOS

Hi,

Thanks for the recent update. Very pleased to see how well MiRack works on an M1 Mac.

One question/request:

I’m trying to use MiRack in a multi channel audio environment on the Mac (Big Sur) and am using Aggregate devices - mainly an ES8 and an internal routing device GroundControl. The issue I am having is that MiRack’s audio device (2,8,16,32) has no way to reveal which channel is linked to which component part of an Aggregate audio device. Now on one level its possible to see that it’s easier to leverage MacOs’s general audio device management - its does however get difficult when you can’t work out which MiRack channel is linked to which part of an Aggregate device. Is it possible to add a little more granularity or device/channel naming inside MiRack?
