I live at Lake Tahoe. I like to track the birds I have seen in the whole basin, but that currently isn’t possible as Lake Tahoe covers two states. I want to keep my lists for each state separate, but also be able to view the birds I have seen at Lake Tahoe as one list instead of as the California side and the Nevada side. So, can you create locations that are viewed in the current hierarchy as well as being able to view sightings from two different locations as one list as desired?
