Static Amount in Row Calculation

Is there a way in Management Reporter to add a static amount to a total for a row definition? 

Currently I have a client who is adding two account numbers to there Retained Earnings line on their balance sheet.  I have to add a static amount to this line and cannot seem to figure out how to accomplish this task.

I am using Managment Reporter 2012 for Microsoft Dynamics ERP Version 2.1.1029.30
