How to erase/undo flight plan changes on 747

How can you erase temporary flight plan changes within the FMS on the Boeing 747-8? I am able to click erase/undo flight plan changes on the Airbus A320neo, but am not sure which button to click on the 747.


how do you modify your departure and arrival locations on the A320 FMS?

I believe that you would enter that information in on the INIT page of the MCDU by typing [DEPARTURE AIRPORT][ARRIVAL AIRPORT]. For example, KSAN/KLAX. However, I’m not sure that this works well with the standard A320 in the game.
