Thanks for your patience. You are on the right track. I've attached the flowchart with the remaining boxes numbered. When you are done with box 7, go back up to box 3, not box 2, because box 2 is done.
I'm not sure what DMC stands for.
I like your use of non-UEB code switch indicators. A category heading on the SS page seems a good choice in this case.
Good job! Flowcharts are challenging.
