volume & mass properties - part/dwg issue

I've created a part using one of my own MMGS template. But when I create a drawing from this part using my IPS drawing template, its still holding on to the metric volume & mass properties in the title block. Is there a way to have these volumes correspond to (ie. converted to) the IMP values, like all my IMP drawing dimensions?
