Anyone know a way to update a CDT column dynamically using a custom rule or func

Anyone know a way to update a CDT column dynamically using a custom rule or function? I realize I can create a script task to loop through the CDT and set the column value. I just wanted a more dynamic way to doing it.

CDTa - can be multiple values.
CDT columns - column1, column2, column3

I want to loop through the CDT and set column2 to a specific numeric value

I reviewed the apply function and the custom plugins - IFM Manager, Set CDT Properties and CDT Manipulation - just wondering the most efficient option.
