Is it possible to par boil potatoes for grilling in a pressure cooker? I have a need for speed in this situation.

Laura Pazzaglia, the author of hippressurecooking.com, has referenced her site on some previous pressure cooking threads (like this one: http://food52.com/hotline/5175-any-pressure-cooker-fans-out-there). Her site includes time charts for different ingredients (http://www.hippressurecooking.com/pressure-cooking-times/) that might be useful as guidelines for not fully cooking your potatoes.
