Lock Fader Levels

Is there a way to lock the fader levels in place? The mixer does not have undo capability and I find myself inadvertently moving faders while trying to move the mouse. I have my console hooked to a 12 foot projector screen so getting the from one end to the other takes a bit of mouse pushing. Sometimes in pushing the touchpad, it grabs a fader by accident. I don’t always realize that my perfect levels have moved until I am listening later and it is a task to get it to sit back down exactly where I left it. Freezing and/or locking the channel has no effect on the faders.

The quick reply is to put an automation point in for every fader (and turn on their automation). Then if you move them they will ping back to the set automation position.
