title: Optaplanner hard link depot with customer
body: <p>I have a VRPTW case where multiple delivery orders are provided. 10 depots are serving 30 customers based on time windows. Each delivery order is hardly linking depot to customer. E.g. ORDER 1 require delivery of 10 units from DEPOT 1 to CUSTOMER 1, ORDER 2 require delivery of 30 units from DEPOT 1 to CUSTOMER 2 etc..</p>
  
  <p>What could be an aproach to make parametrization in XML to link CUSTOMER to DEPOT?</p>
  
  <p>Thank you!</p>
