Extend Dropdown-List for languages

Hi,
I need in for my clients a field where the languages the clients speaks can be selected. As I want a standarized approach I don’t want any employee to write in this field. I would rather prefer a dropbox with nearly all languages where the sales can choose the languages, similar to the countries which exists. I don’t want to write a value-pair for all possible languages. So I am interested in wether there is a ready made solution.

Kind regards.
