Add Drawing Function to Graph Problems

I'm currently studying algebra two, along with a few others, and we find that some problems would be significantly easier if we were able to use the drawing tool on graphs (specifically the lesson about restricting domains of functions, since we need to do the vertical line test and it's rather annoying to keep putting sticky notes on our screens and then having to immediately peel them off so we can move on). The allotted drawing space stops directly above the graph, meaning we're unable to make any marks on or around it (pictured below). This change would be greatly appreciated.
