Allow a way to generate a map from pin point + radius.

Not sure if this would be possible, but it would be amazing if you could select a pin point location on a map (or enter coordinates), and select a radius to draw away from that point.

There's a few places I'm finding are near the boundaries of certain locations - so rendering something that borders two cities this way would be great.

I love the tool as it is, so thank you, but this would be even more amazing :)
