Software for checking ranking in maps/10-pack?

[DiscoStu]

I have a fairly large number of sites targeting local terms, and it's getting to be a pain keeping track on where they rank and how the rankings are changing week to week.

Is there software that can check your rankings in Google maps, and in the 10 pack and show changes (just like there is for the organic rankings)? That would save me a ton of time and make life a lot easier...

I've always just used a spreadsheet or a text file with a clickable link to the search url.
