Add Headers, Row Data, Etc into New Key Schedule

Hey Guys,

I am trying to add in new headers / row data into my newly created Key Schedule (Data from extracted Revisions) and I am running into some issues forming my data into Revit. Any ideas?

I am open to even incorporating custom Python coding if I need to in order to incorporate the custom data implied into it. Thank you again!

Sincerely,
Kevin

P.S. I rather not have to pull fields from another Schedule as I have seen that may be my only option. Not sure (AKA, ScheduleView.SchedulableFields)
