If you mean like 1/4 of the map jungle, 1/4 of the map destert, 1/4 of the map installation, and 1/4 of the map ashland.
"NO"
Jungle has like 5 types of land plus different elevations, plus water.
Ice terain has like 3 distinctly different terains, different elevations, plus water, and ice.
You may have to make do with something like that, or make a campaign, that when one game ends, it goes to another map all together.
Drawbacks......
Multimap campaigns are one person only, unless you create the first part, after it is done invite all players back to the second, then the third, etc...
