Help with a View Function Using the Logitech Yoke Toggle Switch Mapping

Primarily interested in two views I used most but would like to avoid using the keyboard now that I am using the yoke. This involves the use of the END key on the keyboard to toggle btween external view and cockpit view. I cannot find a way to map this toggle from the keyboard to a selected button on the yoke or the throttle quad if desired. Could someone please assist.

Much thanks!

Here is how I have it assigned to my button 6.
