In case of using pickup and delivery, part or all pickups can be in one point (warehouse). If I set service time fop pickup for example 10 minutes in case of 5 shipments - full service time will be 50 minutes. But this is not real situation. Best solution IMHO is to add additional variable to job - access time. In this case I can set access time for warehouse - 10 minutes and service time for each shipment - 1 minute, so we will get 11 minutes in case of 1 shipment and 15 minutes in case of 5 shipments. What are you thinking about it? This is real use case
