single drawing template for inches and metric?

Is it possible to create a single drawing template that will adjust the tolerances when you select a different unit? We currently have a format for A,B,C & D size drawings and one each for metric/english. (I realize we need to make a format for each size) I know I could make a format with the tolerances missing and fill them in for inches or mm but is there any way to automate that by having the parameters reference the units?
