Is there a way that Supplemental calculation can pick up the shortness from the Regular calculation.

Summary:

Hi All,

 The payroll calculation set up for Regular paycheck and Supplemental paycheck are default to 
calculate separately.
In the case of low regular earning, sometimes the earning is not enough to cover the Roth contribution.

 For example - One employee regular earning was not enough to cover 401k Roth.

 The 401k Roth for his supplemental earnings were deducted at 5% properly. 
Although there was an extra money in the Supplement Earning, the shortness of 401k Roth from Regular Earning 
was not made up.

 Is there a way that the Supplemental calculation can pick up the shortness from the Regular calculation if any.
