Improve work order document for freight orders with multiple pick ups

IMPROVEMENT

When you create a freight plan that has one truck executing multiple pickups on the same day, the work order reports only reflect Pick up 1 of 1 for both orders.  We improved the logic so when a multiple orders are associated to the same truck on the same plan, the sequence of pickups will be reflected at the top of the work order.

Example:  Truck A is scheduled to pickup orders #123 and #456 in the respective order.  The work order for #123 will reflect "Pick up 1 of 2" and the work order for #456 will reflect "Pick up 2 of 2"
