.1 Select a Service in the drop-down

.2  Give the Service a Class Name. I used USPS PRiority Mail 12.5x9.5x.5 so know this service has packaging assigned to it

.4 Here you can select existing packaging in Default Packaging that is already in the system

You can then apply the Special Services you want to use with this Service. 

If they are on the Assigned Special Services side you will be able to apply them when shipping.
If there are not on the Assigned Special Services side you will not be able to use then when shipping.
If you select Auto Apply it will always use that special service when shipping.
