Can't Test User Map In Single Player?

Here's a smitten problem I find rather annoying. Unless I'm missing something, in order for me to test a map useing the MED I first must log into Nova and then test my map in LAN. There does not seem to be any listing of test maps in Single player mode.

Hey Charger , thats 1 of the first things I checked out , I made a test map and saved as a coop and a single player and it worked fine , after starting up the game , click on single player and click "instant action" tab at the top of page , your map plus any maps you've beaten in any campaigns should be listed there.. Hope that does it for ya...

Cool...I'll check it out later. Thanks.
