Wouldn't Objaction Scaler - Maz's program in Free Stuff utilities do this? It is usually used to scale up going into Max and scale back to Poser size coming out. If you Import into Poser with any scaling change done then, it messes up any morphs. If you uncheck scaling and bring it in as is, and then scale, you usually wind up at the 2% level, which makes fine tuning difficult. It is usually best to try to get something to Poser scale before import - either in the modeler itself or a utility.
