It's great that matrices can have different units for their column values.

Is it possible to change the default values for the various columns? For example, from kg.m^2/sec^2 to kN.m and from kg.m/sec^2 to kN?

I've tried using the default inverse to eliminate the unit, and, then multiplying the unitless value by the unit I'd like to change it to. The result is the default unit.
