I am trying to do route optimzation calculation with a number of service points. I do need the tour to start at one of the service points and not at a specified depot. (Our customer expects some of his employees to start their work at the first service point, not at their home location)
So far it seems that I need to specify a start_address in the vehicle section. Is it possible to somehow leave this out, so that the tour starts at whichever service point happens to be first?
