Please add the capability to lock/unlock fields/columns for editing by Group Assignment.
While Groups can be assigned with or without editing permissions to a sheet, Columns can only be locked for editing so that only administrators can edit locked columns. Being able to assign permissions that would only allow users in selected groups to edit specific columns would be helpful and roll up to reports.
Use Case: Assign two groups with Editor permissions to a Sheet: Logistics and Programs. There are some columns I want Logistics to be able to edit, but no other groups. There are some columns I want Programs to edit, but no other groups.
Thank you
