Feature Request: remove Zip Code and City from Adress-line

[Kugelfang666]

thanks for this fantastic module. Maybe one idea to improve even further:

It would be great to have a way of modifying the degree of detail for the address line. I've a mirror only small space for this add-on and since I'm just looking for gas stations close by all the addresses beginn with the same data (identical zip code, and city). However, due to space constraints the actual information (stress) truncated.
