Questions about the Heroes 4 map editor.

Guys, please tell me, is it possible to somehow slow down the growth of creatures and/or increase the number of turns on a map?

- Reduce the initial number of creatures. Accordingly, the growth will slow down;
- Track the number of creatures using a script ("Recurring Events") - if the number exceeds the required amount, reduce it. Calendar events on neutral creatures do not work;
- Place neutral creatures under a flag (any hostile one, for the duration of their turn);

"Increase the number of turns" - what do you mean?
