Self-replenishment of bodyguards

[Monkwarrior]

Hi.
I'm doing a campaign without a proper family tree, as the king has only one son below the adult age. The game automatically assigns one "apparent heir".

I've checked in normal size of units, and the bodyguards of all the named characters have 20 soldiers, except those of leader and heir that gradually are replenish to reach 31 and 27.

Is there any way to prevent this and keep the bodyguards in the normal level? (or with reduced numbers after a battle, for example)

No, as far as I know.
