CT Estimated Annual Gross parameter

Hi All.  We have one issue left on our upgrade to the TF90d3 and that is with the CT withholding.  We are finding that the programs are not taking the supplemental wages into consideration when calculating the taxes.  I found some documentation that states "Connecticut Annual Taxable Wage is expected to be passed into BSI TaxFactory via the Estimated Annuall Gross (EG) parameter in the Tax API.  This parameter is expected to include the employee's Connecticut taxable wages for the entire year, including all year-to-date, current and projected regular and supplemental wages."  Does anyone know how to set up this EG parameter within the tax API?  We have asked Lawson, but haven't heard back yet.
