France and DOM TOM Location

Hi guys is about France location.

In france we have DOM ” Departement d’outre mer”= region over the sea. So Guadeloupe, Martinique, Reunin, Guyane is like a region of France with is own zip code. Guadeloupe post code is: 97100 , reunion is 97200.

i multilocation a can choose between France and France Metropolitan. in France The firts means the contry with all regions so the land and the isle DOM. The second metropolitan means only the country, the land.

My problem is i would have France and DOM (Guadeloupe, Martinique, Reunion, Guyane). How can do ?

If i selected multicontry in parameters and choose France and Guadeloupe for example, i get some error to set automatically adresse . And after my search bar do not work with post code.
