SolidWorks>Document Properties>Dimensions>Dual Dimensions>Show units for dual display

My title block shows "DIMENSIONS ARE IN INCHES UNLESS OTHERWISE SPECIFIED."  Inches are my primary units.

I want dual dimensions to display units "mm" for millimeters for the secondary dimension, but not "in" for inches on the primary dimension.

example: 1.625 [41.23mm]

Is there a way to accomplish this?
