Suggestions for a mapping application?

Hey guys,
I’m really scratching my head on this one, since it seems like there should be a very obvious and simple solution, yet I can’t seem to find it.

I have a list of addresses that I want to plot onto a map and have the markers be sequentially numbered in accordance with the rows (e.g. Row 1 would have the marker labeled “1”). Ideally this would be dynamic, so that if I deleted row 3, all the rows after would re-number accordingly.

I can’t believe how frustrating it’s been looking for what you’d think would be an obvious feature of a mapping tool. Google’s MapsEngine Lite comes close, but it only allows you to do sequential letters and colors, not numbers. Does anyone know of a tool or service that does this?

Thanks for the help in advance,
Mike
