More emojis when practice tracking

Under session details, sometimes the available emojis don’t capture how I’m really feeling. It looks like there is room for a couple more emojis. It would be nice if the app allowed the user to add the emojis of their choice. These might better reflect how I’m really feeling when the stock ones don’t quite capture it.

System update: Changed the title from "How are you really feeling?" to "More emojis when practice tracking". Reason: The updated title better matches the scope of this suggestion.
