set_recruit_pool for mercenary unit

[attyla]

Is there possible to use command set_recruit_pool for recruit pools in descr_mercenaries? I've tried to use it, but log doesn't recognise mercenaries recruits pools.
I suppose there is no possibility to use this command for my ends. So - how to make it by other way?

You could just use an event_counter combined with an initial recruit pool. Other than that I don't really see any options.
