Create Calculated Values in Schedules?

Revit’s UI is rather tedious if one wants to make a complicated schedule with many calculated values. Is there any way to do that programmatically?

Did you ever get anywhere with this? I have cot to add a calculated schedule field to over 500 schedules, this would save me hours. I have the formula for the calculated value but pasting it into the field editor 500 times is really time consuming.

I’d make new parameters, calculate whatever with Dynamo, and set the parameters’ value. Then simply show the parameters in the schedule.
