Where ever I played since I play Kemper (2015), the men on the desks offered XLR to connect.
Never got quarter inch cables.
There are converters either way so shouldn't be a big issue although more failure points..
Im still not sure why you need it i.e. what you are trying to do, but I may have missed that.
TBH I've never understood why people need hundreds of performances as it causes lots of issues, balancing rigs and anything you want to apply globally - I'm in 3 bands and use 4 performances but hey that's personal choice.
Not sure if you can use "lock" here as a global setting??
As mentioned earlier, its unlikely you will get a software change as to me its a pretty unique requirement.
Hope you find a solution.
