Not sure I'm understanding your question correctly....
Do you mean move a shape before you stamp it? (That would be two fingers on the shape to rotate/move it.)
Or do you mean move something after it's drawn? (Which would be tapping on the layer with the shape you want to move, tapping it again to bring up the Layers menu, tapping the Transform icon, then moving/scaling with two fingers.)
Let me know if you mean something else entirely.
So you can move/transform a shape only by editing the layer it is in, with all of its objects. Thanks, good to know.
Yes. That's exactly right.
