The option to schedule a report is available from Garden/Pro Plan onwards, for both On-Demand and Saved Reports. 

Please navigate to the Reports tab -> click on the report for which you need to set this up -> click on "Create Schedule" option available next to the Report Name (or) Report View Title.

Kindly note that we do not have this option for "Satisfaction Survey" reports.
