Yes, but you'll need to write the CSS for that. Example as follows.
Code:
.cb_template .cbPosCanvasTop {
height: 400px;
}
That would change it from 200px to 400px height. You can do the same to make it smaller. Use responsive CSS to have multiple sizes across devices, etc.. You can apply this CSS to CB using the built in CSS Overrides functionality shown below.
