Im a bit confused on what the request is?
It relates to the fact that you can only (un) lock CS, DS and NG together. So if you have a preset for your guitar with optimised CS and DS, you can't set the NG per rig (when you find a profile with a very noisy (distorting) amp) unless you waste an fx slot for adding a further NG.
so the request is to move NG outside the Input section, so that it can be set independently from the Locked Input on a rig-per-rig basis.
I cant set up a preset that includes my input routing including CS levels for reamping
You can't? Is it any different than saving any Input preset?
