Sheets inside a workspace are automatically edited from Master Workspace

I copied a workflow form a master workflow. When I am working in the master and I edit a formula on a sheet, the copied workspace sheet is edited too. Is that a feature?

I actually think it would be a great feature in some cases where you have a standard you want everyone to use. On the other hand, this capability doesn't make sense if the workspace is shared say to another department and they wouldn't want the updates because they have different metrics.

I have both cases. Is there a way to shut off the capability?
