“Heroes of Might and Magic V: Tribes of the East”

It’s a pity that it won’t be possible. If it could be reworked, it would be very interesting! And I have another question: how can I divide an army slot into parts, for example, 200 goblins, into groups of, say, 50, 50, 100? In Heroes 3, it’s clear, in Heroes 4, too, but in Heroes 5, I can’t. Why?
