It would be really helpful if you could draw a radius or square block and keep it on the map. Much like how the radius function currently works in 7.6 but instead of the circle disappearing after the rows are marked the circle would stay and ideally multiple radii could be added. This would aide in helping us visually represent different geographic density between different location on the same map. Currently, I export a screen shot while the circle is still there then do another screenshot without the circle then overlay the two maps in PowerPoint.
