Thanks Toby, that’s one for the new features list… but would need to think carefully how one avoids accidentally creating feedback loops! At least if you are patching physical outputs to a stereo input you can see what you have done 
There are other games you could play using stereo matrices fed by a combination of auxes and groups, but the external patch is for now an effective and visible way of doing it. You could use the T80 connections instead of using up MixRack sockets for this.
And Graham, you can patch the LR outputs and in fact just about any signal to MADI using the OUTPUTS / Port B MADI screen.
Hope that helps,
Carey
