You can create a higher contribution cap than the SGL cap by creating an employer contribution that doesn't Apply SGL. If the higher cap is for selected employees, then you will need two Employer Contributions.
You will need to monitor the employee's superannuation contributions throughout the year. Once they have reached your maximum, change the allocation on the employee record to zero for the remainder of the financial year. In the new year set the allocation to 100. Use Manual Calculation if you need to override the calculated value in the last period.
