How do I add "crosshairs" to my figure while I use the Camera Toolbar without them being affected by the toolbar?

I want to manipulate a surface object using the Camera Toolbar. However, I have decided to include "crosshairs" above it (two intersecting lines), so I can maintain where the camera target point is. Unfortunately, when using the Toolbar, I can manipulate these lines (i.e., orbit, pan, zoom, etc.). Is there a way I can include these lines in my figure without them being movable?

Including two "Axes" on a figure while using the Camera Toolbar will result in one camera corresponding to each "Axes", resulting in complex behavior. A better alternative is using the "annotation" function. For example, the below code will create a new figure with the desired "crosshairs":

f = figure;
an1 = annotation('line', 'Position', [0.5 0 0.01 1]);
an2 = annotation('line', 'Position', [0 0.5 1 0.01]);
