If you cannot find a country in the country selection, you can easily add it manually.
To do this, click on Addresses and open the master sheet of any client. Select the Country field and scroll down to the bottom where you can then select ' Countries... '.

A window with the country list appears. Click on the blue plus sign to add a country.

In the next window you can then enter the necessary information on the country to be included. In our example we add Lichtenstein to the country selection.
