Why is there no fingers crossed emoji?

Why is there no fingers crossed emoji? My friend sent me a text and it said "fingers crossed" and she likes to use emojis in her writing so I sent her back "There's no emoji for that?" in which she proceeded to go into a deep depression because there was indeed no "fingers crossed" emoji. Im sure there are many ideas for emojis but this one seems to be one that nobody has ever thought about yet it would probably be a great idea to add to the Apple game. If Apple does not feel this necessary to add I will then proceed to asking Android to add it to their keyboard and then they will proceed into "thinking different" from Apple and rise to the top. Thank you for your time and may the odds be ever in my favor. (P.S. I really want this to be a thing)
