Is there a way to reuse a stamp?

Hey @sworcester, thanks for your question. Currently, it is not possible to duplicate the stamp on Canvas, so the best way to achieve this would be to create an image with the sphere already duplicated and then stamp that image onto your model. Painting must be done before applying a stamp, so creating regions and then going back to paint over the stamp is not possible. However, I can pass these on as feature requests for the Canvas team.
