All records in combobox

[CMontoro]

I've designed a form to register the parametros of a world-wide statistic report
In the form I have a combobox to select by pais, but additionally I need the option 'ALL' for to inform about all countries

How I can include the option ALL in the combobox ?

Thanks
Carlos
