Show Master Meter for Ext In Control Room

We now have a very nice meter section. But it only works on the main mix.
I would like the master meter also to work on the Ext-in in the control room.
Currently you only have a small horizontal meter.
I mix with external summing and my “main mix” is coming back into Cubase via the Ext-in port, via which I also print. A simple “Main Mix meter follows input” would be an excellent quick win!
