I use Holy Nova for dailies that involve multiple mobs, or farming meat for cooking. Bind the macro below to a key and just press it repeatedly. That way you get all three spells cast with one keypress, and your PI and IF will proc any time they are up, rather than having to make a special effort to use them.
