Questions about the Heroes 4 map editor.

1. How can I make it so that only a specific hero can pass through the quest gates, without other heroes?
2. And also, how can a hero pass through without an army and without other heroes?

Task conditions:

1. "has hero" (this army, select the hero's name [pre-assign to the desired hero]) AND "total number of heroes" (this army, equals 1)

2. "has hero" (this army, select the hero's name) AND "total number of heroes" (this army, equals 1) AND "total number of units in the army" (this army, equals 0)

Consider nuances - for example, a hero may have the "Summoning" skill. Therefore, after passing through the quest gates, he can replenish the army daily with summoned creatures.
