No, the system works on a Play Once basis.
You select a map, and you cannot leave until you finish it. When you finish it, you return to 00_rainy_hall_HUB.map.

In case of more maps, the first one should lead to the second, the second to the third and the final one to 00_rainy_hall_HUB.map with a linear progression.
