Hi pranalipatel,
I couldn't find my last input, must did it wrong? Thanks for pointing to the right area for my suggestion.
Anyway, I already clicked the new issue button and put in my happy face icons feature to add-in. Hope is correct this time.
There is icons can be insert here, why not rtmedia too? See what I sent 3 icons here.
Hope this will added and get an email for this update feature. 
Thanks again!
