Character poses and expressions

I would love it if there were a few more friendly/neutral options for the modern illustrated characters in Storyline. Specifically, if they could wave (at another character, at the learner, etc.) and have a more friendly "Neutral" expression that's somewhere between irritated and full-on smiling (I'm looking at you, Camila). With the options we currently have, I sometimes find it difficult to have their poses and expressions match their words.
