iOS - Storyboard - localization - After modifying storyboard, how to sync to other language storyboard?

ios, uistoryboard

Solution

If you are using iOS version >= 6 (and Xcode >=4.5), you can use a single storyboard for multiple languages, i.e., do base localization + the usual string localization. Doing so, you have only to care about the localized strings in string files.

For a guide, see e.g. here.

Problem

I know how to turn on storyboard's localization. The problem is I don't know how to sync all localizaion storyboards, after main (English) storyboard is modified. Is there any shortcut to sync them? Do I have to do all those modifies again and again in over TEN language storyboards? My condition is: I have a project with over ten localizations. After I released it on AppStore, we have new user requirements.Then, we start program next version app. After I completed tons of improving and creating on stroyboard, I feel desperate to facing other language storyboards.
