We can only have 3 custom characters uploaded to the brilliant new ActorCore Mobile view & web embed. It's great to be able to use a drop-down and select from our library of motions. However with the transparent background and other UI elements hidden, those motions go to waste.

My suggestion is to allow an index choice of animation within the iframe embed code: (example)
<iframe id="character01" frameborder="0" allowfullscreen mozallowfullscreen="true" webkitallowfullscreen="true" allow="autoplay; fullscreen" xr-spatial-tracking execution-while-out-of-viewport execution-while-not-rendered width="590" height="432" src="https://actorcore.reallusion.com/Player/player.html?mainid=ATCg00tl4gg7b9nn0cgzw&playbar=0&control=0&titlebar=0&bg_transparent=1&pan=0&zoom=0&rotate=0"></iframe>

...with &animindex=1 or something similar to pull from our list of motions.
