99% Confidence Calculation

Does anyone know how to run a simple linear model using a 99% confidence instead of the default 95%? I can make the change with the "Fit Y by X" but not in the "Fit Model"

You can save 99% mean or individual confidence limits for prediction by holding down the shift key while you click the red triangle pull down menu for the dependent variable and then Columns > Mean Confidence Limits or Columns > Individual Confidence Limits. You will be asked to supply an alpha level which, for 99% CL would be 0.01.
