Just starting an orcish themed army. I want it to be led by savage orcs ( so all lords and heroes will be savage orcs, while the rest of the army will be composed only from orcs )

I am just wondering... Is the GW box for orcs shamans allows the building of a Savage orc shaman on foot and on boar, is it made to allow only regular orcs shamans?

Thanks and sorry if that as already been spoken of
