+1 bump to this thread.
The Everything IO ecosystem definitely needs this as an option. Today, I was trying to switch a showfile with everything sourced from a DM48 to 3x DX168’s. I tried saving a preamp only scene with the mixrack and recalling it once softpatched and… nothing. Ended up having to just write everything down and manually input which just seems like a waste of time when these consoles have FPGA chips and 800+ routing paths.
Not sure the best way to do this? Maybe a global input preamp store and recall in the utility section that does a snapshot of all 128 input channel settings.
