If you have a master template with multiple layouts and you wish to find out which one is the most used, there is currently no report that can show this information in Vuture. However, such a report can be created by request.  If this is a report you would like to view, you can reach out to your CSM to work with internal teams to get the report.

See the article linked below for an index of reports available in Vuture:
