You should get used to using "Working" Schedules. We have Master Schedules for a lot of our Categories, like Doors, etc. where we use to drive changes in the Main Sheet Schedules. Not only can you hide Columns, you could use Calculated Parameters to drive changes in the Main Schedule. For example, the YES/NO value on a Schedule is hard on the eye, so we have Calculated Parameters in the Main Sheet Schedule to create a '○' instead of a YES, and leave it blank if it is a NO. The checkboxes for each of these are controlled in the Master Working Schedule. Once you check the box, the symbol will appear on the Sheet Schedule.
Once created though, you have to really enforce much needed care to your team to make sure they understand what to change.
