Improve DPI of Map View in Reporting

When using Workflow to generate a report with a map control box showing the extent of the map view in a web app builder application, the resolution of the resulting report PDF of the map view is extremely poor. Can you please increase the resolution or DPI of the map control box in the PDF report that results from running the "Create Report" tool within workflow. Or allow the user to set the DPI of the map view export?
