A workflow enhancement that is similar to the Change Cell Value.  However, instead of changing a cell, copy it to another cell.  
Use case: I have a formula that calculates a date.  However, I want to keep the initial value of the date and therefore, don't want to reference the date formula because it will change.  A workflow enhancement that would allow me to copy the date to another static column when its first calculated would go a long way.  The way I do it now is complicated.
