of course, you can change the level you want manually (scrolling with the mouse middle button, or triggers with gamepads) or just wait a few sec to have the next one, it always have been like that. It's just like the main online menu.
you have 3 levels each (3min,5min,10min = 3 tiles) per mission "variation" (for miami you have 2 variations of the map, one with and other without the "Parole, parole" target).
