In the Eden editor it is possible to set a scenario name/title for the given mission as set under Attributes -> Presentation -> Title. Once set, the name will appear during scenario selection (briefing) and during loading of the mission.
When saving as a non-binarized (i.e. text-based) scenario file which includes options from the Multiplayer section in Eden (e.g. Multiplayer -> Type -> Game Type), the scenario name no longer displays correctly during scenario selection, instead defaulting to the scenario file name.
A video displaying this phenomenon can be seen here.
