SMCP now includes a button on the 'Configure Work Order' screen labeled 'Clone work order'. If you've just created a work order, and none of the items have been 'used' on the job, you can add a copy of this work order, for the same technician, on to any of the next 14 subsequent calendar days.
You'll be presented with a list of the next 14 days, each with a check box alongside. Check the days you wish to extend this work order on to - this will create identical work orders (same order, same mechanic, same items, etc.) on those days that you select.
