I like the OSMand approach: whenever you change something you get an extra prompt on the bottom of the screen whether you would like to make the change in all other profiles (driving, browsing, walking, public transport, cycling etc) or keep it only here or revert, as pictured below:
go to More Actions by either clicking the FAB (floating action button in the bottom-right corner of your screen) or […] in the top-right corner. You should see an overlay menu with extra actions, within them you’ll see Random and Random NSFW.
