Map A+B to separate button#985

The A+B input is unintuitive and weird to press, and oftentimes leads to misinputs of either button if timed slightly wrong. Could we please map this to a separate button if we have space for it? I have a whole shoulder button that’s going totally unused, and being able to press a separate button that I know won’t have collisions with the other two would be a godsend for input consistency.
