I have a question regarding editing CDT related process variables for a running

I have a question regarding editing CDT related process variables for a running process.
Editing non CDT process variables is straight forward, but when it comes to editing the CDT process variables (for a user task say), for a currently assigned task, it appears that it cannot be done. I have tried editing the process and creating an exception to go down a path to a script task, but the exception is never fired. I understand that I can alter the flow after the currently assigned task to update the CDT process variables via a script task, but that will not help me if they want the CDT process variables to be updated immediately from the currently assigned task.
Hope I have been clear with what I am trying to accomplish. Anyone have any ideas?
