Thanks much for the offer, but please don't do it just for my benefit. I can easily use Google maps to get the street address and then manually input the address into iG. I thought if that process could be automated it would be great, but apparently the limitations of iG won't permit it.
One thing that would be nice would be an easy way to display the current zip code so it could be input to the Google map search request. I suppose, though, that it's easy enough to just go to the gas plugin to find it.
