Insert pages in the middle of the document

It would be great if my students could insert a page in the middle of the document to add a picture of their work. When taking a test, they could insert a new page immediately after the problem they are solving.

tip: screenshots are copied right after they’re taken so if they take a screenshot of their work, it can be pasted right into kami

If I give a test and students do work on another sheet of paper, I want them to be able to insert that after the problem. Often it is too big to go on the same page.
