When you select this command, the AstroGrav locations dialog will be displayed.

The AstroGrav locations dialog allows you to add and remove your own locations to supplement the supplied ones, and also to change the units used for latitudes, longitudes, and altitudes.
To add one of your own locations you use the New button, and to remove one of your own locations you use the Delete button. To add a new location, you need to specify the following five items of information.
In addition, there is a Use this as my home location checkbox that allows you to specify that the currently displayed location is to be made the default location for generating ephemerides with the Window / New Ephemeris... command.
