[Koha] OPAC language selection

Is there any way to change the order of the languages in the opaclanguages system preference or set the default language for the OPAC? It says the top language will be tried first, but we'd like to have the OPAC open with a language that's lower on the list. I was able to change it by editing the value in the database, but was wondering how you could set it from the Koha staff interface. -- Tim McMahon Technical Services West Liberty Public Library
