I would love to help you with this question, but I don't know the answer to it myself. If you post your question
here in the Development Support section (rather than just the development section), you'll get a lot more help. It also keeps the forum looking tidy and the mods/admins happy :p
As for attempting to answer your question: I'm pretty sure (maybe 75% confident) that they automatically load saves from the CS played/saved. You could actually test this out by choosing "Save & Exit" instead of just "Exit" when you leave one of your maps, then try loading it.
I hope that helps a bit :)
