Copying didn't work for me either. But booking one person at a time for overlapping times did. Have you tried that?
ETA: The times I was able to get are 11:40-12:40 for 1, 12:10-1:10 for 1, and 12:20-1:20 for 2. I originally had 1 from 11:10-12:10 and 1 at 12:10-1:10, and 1 that fell in between, but then that 12:20 slot for 2 opened, so I moved two of us into there. I'm now hoping to get the 11:40-12:40 slot moved back just a little, but if not, we have a good 20 minute overlapping window that works for us.
To get these times, I moved my other two FP+s (7DMT and Splash) to late evening, which opened more A&E morning slots for me. When I had those other rides in the morning, I was limited to afternoon and evening A&E slots. After I schedule A&E, I was able to move 7DMT back to where I wanted it with no problems. There was plenty of availability for it and Splash, which I also moved back to where I wanted it.
