There are no dedicated way to do, nothing in «plugin API» system

Then you need to use Yii model directly

See www.yiiframework.com/doc/api/1.1/CActiveRecord and github.com/LimeSurvey/LimeSurvey/blob/ma...els/QuestionL10n.php

If you want to force value : www.limesurvey.org/manual/Plugin_events#Specific_Model_events : beforeQuestionL10nSave surely.
