The answer, as far as I know, is partly.

The stencil feature essentially makes copies of items on your canvas that don't sync when changes are made.

The shared layers sync, but only sync at the level of the entire layer, not at the "object" you are likely thinking. Move things on the layer and they move on all canvases

SO if you can use the shared layers to create your objects, they will do the trick, but it isn't as flexible as being able to have objects that can be placed and moved in multiple canvases (like stencils) and have them sync (like shared layers).

At least that's how I know it
