I often want a study region to be defined by zip codes, but I choose which zip codes to include based on a drive time or other region on the map.
The main problem is that some zip code regions are so small that it is nearly impossible to find them using the method of defining the region by selecting zip codes from the map. Trying to find them all by zooming and scrolling is both tedious and error-prone. (The alternative method of selecting them from a list entails finding each zip's location, which is also tedious when the list is long.)
I suggest that BAO add a feature that will automatically select all the zip codes (or other region types) inside a polygon or drive time.
