                    Unlike the other CRUD private functions, CREATE has an additional PassThru
                    This is for granularity between the public and private functions as some CREATE actions may require the sys_id in order to perform other tasks, while not necessarily wanting to return output to the user
                    A good example of this is New-SNOWUser which features adding a photo to the user record (it's a second rest call after creation of the user)
