Scott's wasnt, by definition, control. Peter's was a scar so not healing of an injury but mastery of his physical form to correct his face.

That leaves us with what Derek said. If not unconscious a werewolf can delay healing. If unconscious it happens automatically.

Then we have at least two incidents where healing was not automatic and had to be "jump-started" by inflicting an additional injury. Most of this points to it being more difficult and rare than a general ability.
