Need to model in extra day in the lead time to provide allowance for packaging etc. without impacting the resource load

Hi, 

The client requires an  extra day post manufacturing, for packing etc, to ship the goods out. 

This extra day needs to be factored in while promising the delivery to the customer. What is the best way to model this so GOP can add an extra day when coming up with the SSD, at the time time this extra day should not consume resource capacity, 

If we use Fixed Lead time in PIM, will that work. Does the FLT consume resource capacity?
