Toonboom equivalent of Flash's wireframe view?

Apologies if this has been posted before, but I would like to know if there is a way to make a layer into either an outline, or else somehow see-through, in Animate. Particularly because I would like to draw a body part (an arm in this case) behind the body, and still be able to see the form of the body and the other arm for reference. I could drag the arm layer in front of the other layer, but that wouldn’t be quite the same thing.

Never mind, turns out you can set locked layers to appear as wireframe in preferences.
