We currently have a standard autoenrollment scheme set up.  We have now offered a salary sacrifice scheme for our employees if they wish to join.  Can I please get some advice on how to set up this additional scheme - our pension adviser said 'its just a drop-down' and suggested I wouldn't have to set it up as a separate scheme but I can't find any guidance.  In software I've seen previously you would have the two schemes set up and assign whichever is applicable to each employee.
