CAD Payroll Earning codes 7.3A

Hi,

over time, there have been different earning codes created for the same type of earning (HOURLY, H, H1, etc...) the key differences have been the GL Distribution...dont' know why.

Is there a tool, like Account Code Changer or Vendor Number Change that could change/consoidate historical activities for an employee in the same manner?  If so, can yo please direct me to it.

thanks
