Can I customise the ability for certain line managers to see certain data based on roles, location, etc.?

Sharing of survey results and online reports is done based off the organisation hierarchy. It cannot be done based off attributes such as location. As a survey manager, when you share survey results with line managers, you can ensure that they only see their relevant team’s data. If any comments have been hidden by the survey manager, then these will also not be shared with line managers.
