Changing Appearance During Animation

Hello, 

I created a lovely animation in SolidWorks with parts hiding, showing and changing color. I used the "advance export" option to load this into Visualize. 

Visualize recognizes that there are properties titled, "Appearance" and "Opacity" from the SolidWorks import. However, there are no options to control these properties in Visualize. 

Is it possible to change the appearance of a part midway through an animation in Visualize? 

Any help would be greatly appreciated.
