The only thing I am aware of in Paizo material is a Barbarian rage power called
Intimidating Glare, which allows you to make Intimidate checks as a move action.
Edit: Not directly related to the question, but maybe helpful. The APG has 2 feats that allow you to situationally make free Intimidate checks.
Dreadful Carnage gives you a free Intimidate check when you drop an enemy to 0 or fewer hit points against all enemies within 30 ft.
Enforcer Gives you a free Intimidate check against someone when you deal non-lethal damage to them.
Also, those are Pathfinder Specific answers. :)
