It depends on your perspective. There might be an easier way for you but it woudl require some additional work for somebody else. Unfortunately the real issue here is that there isn't a simple turnkey solution for this right out of the product. Here is another way I can envision this working is by doing the following:
1. Have a developer on your create a custom audience based on a profile script that looks for the specific values for the profile parameter: profile.geolocation.zip (Profile and variable glossary)
2. You would then just apply that audience.
I completely agree that this is a great idea to have as part of the product. To further facilitate this discussion I've submitted a feature reqeust for you here: Feature to extend audience +10, +20, +50, +100 miles of one Zip Code please help it get some traction by voting and adding your comments to it. Much appreciated! Hope this helped you.
