Add pages in Drawing- feature request

I have been co-teaching with the art teacher on symmetry. The math coach is especially impressed that students are learning about reflective and rotational symmetry with all of the Express options. 

We plan to print student work and would like them to be able to pick their favorite. The problem is, that they can only turn in one page on the assignment. If drawings allowed for making additional pages, students could make several pieces of art in one place and turn it in.
