Ability to duplicate existing built reports to easily ammend for different services/departments. Say I wanted to see DBS record for department A, and then for department B on seperate sheets. Rather than having to keep changing the filter I would just easily have a Query entitled DBS Department A, then duplicate this and rename DBS Department B.
Also, giving non admins (managers) access to queries section would allow them to build/run their own reports straight from PeopleHR and not have to use the API which is more complicated than it needs to be.
