X32 independent gain on copied channel


Hello all, I am new here. I have been using the x32 for a few years. Love the board and software. Recently, we have begun to live stream so I split our board. I copied channels 1-16 to 17-32 so I could mix a separate feed for streaming. I wanted complete control from the gain down. Is it possible to adjust these separately? Can I implement the HA gain split without an external mixer? Any help would be greatly appreciated. Thanks.
