That is available on all maps except live map if I am not mistaken. The GC logo on the left side of the map and the circle
I suggest using maps compare for that. If the county filter gives to many caches and results in a slow map use the Center/radius filter. Coordinates, gccodes and locations that google understand can be used
Don't forget to add a filter to include disabled caches because they are needed.
Remember that only myst/multis etc with corrected coordinate shall be considered. There will be circles for all caches corrected or not and event.
Filter manually by looking at the map the source of the circle.
Don't forget physical stages of multis and mysts. Thay cant be added to PGC.
To get a solution with all circles GSAK or some other program has to be used. (and you have to have solves all caches and stored all stages)
