If you want to make changes to a Secureframe-authored control that includes removing certain mappings you now can through the duplicate control flow.
This will create a custom control with the Secureframe-authored control as a starting point. By starting with the mappings of the Secureframe-authored control, you will not have to re-do all the mappings that still make sense for your version of this control.
After the control is created you can update, create mappings, or delete mappings as you see fit.
