Xcode: best way to localize one of the "Other" languages?

Question

In Xcode 5 > Project > Info > Localizations one can pick a language/region from Other section. Can one localize an app for a region/language that is not among the 32 languages found under Settings.app > General > International > Language without any extra code? And what about InfoPlist.strings and its CFBundleDisplayName localized to a region?

Take Belarusian (be), for example. Can Xcode use be.lproj at runtime without any additional code (on my part)? Or must one manually pick the locale, i.e. using [[NSLocale currentLocale] localeIdentifier]?

Apart from Localizable.strings (for which one can provide code, if need be), I'm mostly concerned about CFBundleDisplayName: can CFBundleDisplayName be localized to one of the Other languages/regions? As far as I can tell, InfoPlist.strings (and CFBundleDisplayName within it) can't be manipulated from code.

I could have a separate Target for each of those Other languages:

• That is, localize those 32 supported languages under Target 32 (for which Xcode can automatically pick correct .lproj directory).
• And Belarusian goes under say Target Be (and has only one Localizable.strings and InfoPlist.strings)?

Obviously, this would mean a lot of targets (and tiresome submit procedure). Is this multiple-targets approach the best possible?
