How to animate simplified then add content like clothing, hair, etc afterwords to your character rig

Is this possible in Animate CC? Was going through some content today from the Animators survival kit. I see that your taught to animate simplified figure and get the keys down first. Then extremes with a very simplified figure. Once it's animated, then you go back and think about clothing and everything else. How can you translate this technique to animate cc? How can you animate the scene with simplified figure for timing, and then go and attach items and cloths later? This would help my students be able to focus on a few things at a time then many. Thank animate and animation experts.
