Hello xavier,
It is not possible to do in Viewer at the moment.
However, if you are still in Metashape Pro interface, you can draw the shape in the area or interes or put the new marker in the point of interest and use Filter photos by marker or shape option - it will display the images in the Photos pane that contain the selected shape or marker, so you can look through these photos (use PgDn / PgUp keys for faster switching the images in the Photo view mode).
