Just a follow up, the driver's 1 (rear shock medium/ skis soft) and driver's 2 (rear shock firm/ skis medium) is working out well for me in the mountains. I normally use driver's 1 for general mountain riding and driver's 2 for climbing. Driver's 2 helps keep the front end down somewhat more during a climb, without having to go down the rabbit hole of trying to get in/out of lock out mode.
Like Chewy22 above I just leave suspension in green mode and can quickly toggle between soft/medium/firm (for trails), and driver's 1/driver's 2 (mountains). I find that when using the ATTAC in this manner, I like it a lot more and use it constantly throughout the day when conditions change.
