You can create a ON MISSION START trigger that creates a radio item (RADIO ITEM ADD). Name it to whatever you want to show in the F10 menu. Set the FLAG to a number, lets say 5. Set the VALUE to 1.
create a NO EVENT trigger. Under CONDITIONS, set to FLAG IS TRUE and the FLAG set to 5. in the ACTIONS select LOAD MISSION, click the OPEN button and select the mission you want to load thru the radio menu.
