How can we avoid benefits deductions on the separate check

Hi,

We have to retro pay for the employees and need to pay on retro amount on separate checks.

We are able to issue a separate check but benefits deductions are coming out on the separate check as well. I believe this is because of deduction code config deduction taken out from a separate check is selected. Is there a way without changing all the deduction codes config all the employee's separate checks not to deduct the benefits deduction?

Your help is much appreciated.

Thanks
