I know I can adjust their eyes/eyelids expression by right clicking and going to 'set skin' and I can adjust their mouths by right clicking>set body groups>mouth. Is there any other controls for their expression that I'm missing or is that it? Because for most models there is a list of facial controls in the 'unknown' section of the model but Pearl and Marina don't seem to have those. I also see plenty of people in the comments having the same problem I am.
