When you make a map you have to fill in a tick in a box to say which map type it is. If you have create a map with all the elements of the gametypes in it you can tick more opts but if you want to get more maps in to 1 its a nogo
To c what i mean with the tick a box look at the "basic DFMedguide" i made. The ss is in it.
