掲示板 Forums - advanced kanji using handwritten put in

I noticed when quizzing the other day that when I wanted to answer 淹れる using handwritten input the kanji didn't show up as a suggestion (ended up just typing it using my keyboard). I assume that it didn't show because it is a 漢字検定１級 kanji, but it slows me down significantly while quizzing not being able to write it. Would it be possible to add more complex kanji or even as another check box to not confuse other users with kanji they don't need?

I have been really liking the feature since it helps me to actively recall how words are actually written
