In the new Intelligence Suite tools the PDF Image Template tool allows a user to select portions of the document to be OCRed downstream by the Image to Text tool, however there is no way to currently zoom in and out of the document to draw the annotations, the only way I have found is to stretch the configuration window and the PDF width will autoscale, but doing so will lose the annotations.
So the request is to have zoom in/out and pan options within the configuration pane to improve the UX.
