Ability to draw a circle on moving map chart

I would like to think that having the ability to draw a circle of x radius on the chart for plotting TOD would be very helpful. I fly GA aircraft and do not have an FMS that can show the optimum TOD. Being able to draw a circle around the bottom of descent would make it much easier to begin a descent without having to constantly monitor distances on the GPS Flight Plan.
