Probably not. And I couldn't find it from the the mapedit.pdf located in \Dominions II\doc\ . It does contain much information for how to make some provinces special, adding sites or special defenders, spesifing independent type for a province, spesifying start locations etc. If you were to make that kind of version of your map available, you would better also include a version with no specials except start locations, so that it is more accessible in multiplayer.
