Hi Dave, I don't this would be possible unless you had a Set variable action in a workflow transition. That way you could set up your third variable and ask it's value to be set to yes, as well as adding a condition, that your Customer Controlled variables have to have a value of 1 (assuming they are set up as Yes/No) variable types
Your suggestion makes sense, I hadn't thought of that. One idea I had was to change from individual checkboxes to a dropdown showing the customer names that could be selected for customer control and adding that variable to my column set, but I'm slightly afraid that my users might get confused that they have to select something from that field. I think for now I'll leave things alone and revisit this in a few months.
