I built a door schedule that only shows doors on the first floor. Now I want to duplicate it and change the new one so it only shows doors on the second floor. Since there is no Duplicate function, I tried several things including Importing the first floor version and changing the name and criteria. After I did that, my project lost every schedule there was, so I quit without saving. I tried other things but still haven't had any luck. Do I have to build the second schedule from scratch?
