Let me explain, I need to enter the appointments of the day for different operators
example : in a mechanical workshop there are 4 workers, one specialized in various mechanical sectors, electrician, car repairer, tire dealer
a car can be from 3 pm to 4 pm at the mechanic and then go to the tire shop at 4 pm and finish at the body shop at 6 pm
the colors of the appointments are used to define the type of work performed
so i can't use colors to differentiate operators
any solution to solve?
