Crop mode by pressing the button canon EOS 650d

[fotap]

Greetings dear community, I am glad the beautiful features: crop mode in my camera canon EOS 650d. But to use it in a wedding reportage once, since it is necessary to go into the menu to change. In the dream, I see that the crop mode is activated by pressing any button on the camera, such as a set. Is it possible to implement such fukntsii - switching crop mode in the camera EOS 650d by pressing the buttons on the camera?
Very grateful to the community for the development of magical Lantern, and thank you in advance for your answers.
