Multi used of country field in a profile ?

Hello,

i would like to use the country field not only for the user address but also two more times :
(example for a traveller profile) :
- countries already visited
- countries planned to be visited

and i wonder if it's possible :
- to use country field more than one time in a profile ??
- to multi-select countries in the field ??

thanks in advance
Loïc

i have checked the documentation but all custom fields page are landing in wrong page : profile completeness module see attachment
