Just created an account for this exact problem. (and sorry for replying to an old thread)
You are totally right. I use a Behringer x32 for my church, and having the ability to route post-fader aux busses back into the main LR (to then be sent to a matrix for mains/fills/subs) is AMAZING. It is like using a subgroup, but better. This has been especially useful for double dipping in FX returns. I can use the same reverb effect but have a different return value for the room / livestream. I wish I could do the same thing on the SQ-5.
However, I have gotten similar results by routing all the channel faders to a post-fader aux bus- then the buses to a matrix (skipping the main LR entirely). I then used a DCA to control all 3 matrices like a master volume. I hope this helps! 🙂
