Hidden Units Map Question w/ Conflict of Heroes

[fatgreta1066]

Hi,

If I'm playing a scenario with hidden units, using the player A map for instance, is there a way for me to reveal units to my opponent one at a time, as he exposes them? Or do I simply drag them from that map to my map. The reason I ask is, if not, then the hidden units are still done on an honor system, and I'm not sure why it doesn't make sense just to write them down, as you do in the face to face game?

Thanks,

Chris
