title: How to change source translation in yii2 in lajax/translatemanager module
body: <p>I installed <a href="https://github.com/lajax/yii2-translate-manager" rel="nofollow noreferrer">this translate manager</a> on my Yii 2 Advanced application and I'm trying to translate source variant. </p>
  
  <p>Imagine that I have 2 languages - English and German. In my code I have <code>Yii::t('frontend', 'Hello')</code>. And I translated it to German like 'Guten morgen' and it works (word 'Hello' changes depending on the current application language, and now - if it's <code>En</code> - it's 'Hello' and if it's <code>De</code> - it's 'Guten morgen'). </p>
  
  <p>But now I want to translate source word 'Hello' and <code>En</code> variant will be 'Hi'. I did this but word does not change. What do I have to do?</p>
