Hi @nmac! You are correct. At this time the armed modes available with Alarm are disarmed, home, and away. You are able to, however, choose which Alarm sensors will be included in that mode, as well as the option to bypass other sensors when arming. Bypassing could be a solution as long as you do not have too many sensors, as this would have to be done manually. Check out our help center article about bypassing for more information.
We appreciate your feedback on this functionality, and think it’d be a great addition on the Feature Request board. Feel free to add this and any future feature requests there. This will help us to organize and share your requests with our teams here, as well as allow other neighbors to comment and add interest, all in one place.
