Hey! Is there a way to show more difficulties for custom campaigns?

screensingleplayercreate.json
has
Background/DifficultyDropDown
as difficulty tab and

campaignscenarioselection.json
has
Background/Data/GameSettings/Data/DifficultyDropDown
as difficulty tab

but i can’t replicate or overwrite those widgets in the campaign_layout.json file
