I use reports as a way to minimize the amount of supporting sheets by creating a master sheet where the project manager can select which supporting sheet should be visible to the client at a time and the client views those in the report. Using WorkApps, so the client only ever sees the report and not the master sheet.
Depending on project scope they might need one or another of these "reports + master sheet" combinations. As of now, the report must be selected for all projects.
