@Dev's/Rioters Pinging skills for cool down but doesn't say charges

Example would be playing akali. I ping my R to let people know if its down or up, but what about charges? There are plenty of times where i'll have only 1 charge on my R, but my jungler see's I have R up and think i'm all set/ready for a fight. Obviously I can type/ping him off, but since pinging your skills is an option now, I figured it would be nice to add in not only cool down timer but charges as well on skills. I'm sure there are other champions who might have this issue as well. Also if this isn't the right place to post this, I apologize.
