Yes, this is possible:

 Open keyboard shortcuts editor (Ctrl-K on PC, Command-K on Mac), go to Zoom-Pan section,  and add shortcuts for Zoom In/Zoom out (+ button, than corresponding input, in your case wheel rotation, in input capture dialog).



With default settings, Mouse Weel will scroll (zoomed) image in window, while Shift-Wheel configured for Zoom In/Out
