Adding a flashcard from an example sentence


Hi, I'm wondering how to pick an example sentence from a dictionary entry and easily create a flashcard for it.

My workflow is:
1. See or hear a word in the world (e.g. in 喜羊羊)
2. Look that word up in pleco
3. Add that word to my flashcards

I want to go one step further and
4. Add an example sentence as a flashcard so that I get more practice than just the word, and also get the word in context.

My review process is currently to use audio-only flashcards and need to guess the English translation.

I haven't been able to figure out how to do (4) easily, any ideas?
