Mixing in Mono in Cubase Artist 7.5.30

I am using Cubase Artist 7.5.30 with a Steinberg UR22 interface. Is it possible to flip between Mono and Stereo somewhere while mixing ? (I wouold like to mix in Mono and the flip back to Stereo when I finished mixing)

create a mono group track

select the output of the stereo track to the group

toggle between the two outputs

Just use a plug in with a mono button…Steinberg Stereo Enhancer has one or there are various 3rd party options available (for example: http://music.service-1.de/html/m-st.html).

Thank you so much ! Works like a charm. Much apprecioated !
