Add the ability to define whether a Service Order is raised/shown.  This could be done in a couple of ways to assist customers.

1. Overall Setting to toggle Service Orders on or off
2. Secondary setting to only show if 2 or more calls/requests are chosen
3. By Service Action Option.  (maybe for calls only?)

The reason for this could be to turn off service order numbers being shown to a customer when logging an incident via the service catalogue as although they have raised it against the SA they may not feel they have 'ordered' something.  Having 2 separate numbers adds confusion to the customer when logging which may not be necessary.
